Neutral chiral cyclopentadienyl Ru(ii)Cl catalysts enable enantioselective [2+2]-cycloadditions

Cyclopentadienyl ruthenium(ii) complexes with a large number of available coordination sites are frequently used catalysts for a broad range of transformations. To be able to render these transformations enantioselective, we have designed a chiral neutral CpxRu(ii)Cl complex basing on an atropchiral cyclopentadienyl (Cpx) ligand which is accessed in a streamlined C-H functionalisation approach. The catalyst displays excellent levels of reactivity and enantioselectivity for enantioselective [2+2]-cycloadditions leading to strained chiral cyclobutenes, allowing for catalyst loadings as low as 1 mol%. A very strong counterion effect of a bound chloride anion transforms the corresponding unselective cationic complex into a highly enantioselective neutral version. Moreover, by adding norbornadiene at the end of the reaction the catalyst can be recovered and subsequently reused.

Selective hydrogenation of ruthenium acylphosphine complexes

Hydrogenation of a benzene ruthenium chloride dimer in the presence of novel acylphosphine (phosphomide) ligands resulted in the formation of corresponding ruthenium(II)-benzyl phosphine complexes. Here, selective reduction of the carbonyl group to a methylene unit takes place with molecular hydrogen under mild conditions in good yield. This approach provides an alternative synthesis of ruthenium phosphine complexes of benzyl and heterobenzyl phosphine ligands.

Ruthenium-catalyzed oxidative homocoupling of arylboronic acids in water: Ligand tuned reactivity and mechanistic study

Molecular catalysts based on water-soluble arene-Ru(II) complexes ([Ru]-1-[Ru]-5) containing aniline (L1), 2-methylaniline (L2), 2,6-dimethylaniline (L3), 4-methylaniline (L4), and 4-chloroaniline (L5) were designed for the homocoupling of arylboronic acids in water. These complexes were fully characterized by 1H, 13C NMR, mass spectrometry, and elemental analyses. Structural geometry for two of the representative arene-Ru(II) complexes [Ru]-3 and [Ru]-4 was established by single-crystal X-ray diffraction studies. Our studies showed that the selectivity toward biaryls products is influenced by the position and the electronic behavior of various substituents of aniline ligand coordinated to ruthenium. Extensive investigations using 1H NMR, 19F NMR, and mass spectral studies provided insights into the mechanistic pathway of homocoupling of arylboronic acids, where the identification of important organometallic intermediates, such as sigma-aryl/di(sigma-aryl) coordinated arene-Ru(II) species, suggested that the reaction proceeds through the formation of crucial di(sigma-aryl)-Ru intermediates by the interaction of arylboronic acid with Ru-catalyst to yield biaryl products.

Synthesis of half sandwich platinum group metal complexes containing pyridyl benzothiazole hydrazones: Study of bonding modes and antimicrobial activity

Pyridyl benzothiazole hydrazone derivatives containing ruthenium, rhodium and iridium complexes have been synthesized, characterized and evaluated for antimicrobial activity. Metal precursors of the type [(arene)RuCl2]2(arene = p-cymene, benzene), [Cp?MCl2]2 (M = Rh/Ir) and pyridyl benzothiazole hydrazone ligands (L1 and L2) have been employed in this work. Complexes containing ligands L1 in 1:2 (M:L) ratio yielded only one type of cationic mononuclear complexes whereas ligand L2 in 1:2 (M:L) ratio yielded two types of cationic mononuclear complexes. In same manner ligand L2 in 1:1 (M:L) ratio also yielded two types of binuclear complexes with different modes of binding. All these complexes have been characterized by analytical, spectroscopic and single-crystal X-ray diffraction studies. Antibacterial studies of ligands and complexes have been carried out and were found to exhibit potent activity towards gram-positive and gram-negative bacteria.

Ruthenium complexes of triazole-based scorpionate ligands transfer hydrogen to substrates under base-free conditions

The first ruthenium complexes of bulky tris(triazolyl)borate (Ttz) ligands were synthesized, fully characterized, and studied as transfer hydrogenation catalysts. The structures of the complexes were (eta6-arene)RuCl(N, N), where in each case N,N is a kappa2-Ttz or bis(triazolyl)borate (Btz) ligand (arene = p-cymene (1, 3, 5, 6), benzene (2), C6Me 6 (4); N,N = TtzPh,Me* (1, 2), TtzMe,Me (3, 4), Ttz (5), Btz (6)). All but 5 were crystallographically characterized, and notably for 1 and 2 a rearranged ligand structure is observed (as indicated by an asterisk). These complexes were all effective catalysts for transfer hydrogenation of aryl ketones in isopropyl alcohol with base co-catalyst, with rates that were accelerated by moisture-free conditions. Complexes 1 and 2 are also effective catalysts for base-free transfer hydrogenation, and with 1 hydrogenation of several base-sensitive substrates was demonstrated. The ability of 1 to serve as a hydrogenation catalyst without base is attributed primarily to steric bulk, and a preliminary mechanism for formation of that active catalyst is proposed.

Polar cofacially fixed sandwich complexes: Do they demonstrate second harmonic generation (SHG)?

For the purpose of possible second harmonic generation (SHG) a cationic and a neutral sandwich unit were cofacially arranged in a three-step synthesis starting from 1,8-diiodonaphthalene. First, 1-cyclopentadienyl-8-iodonaphthalene (2) was formed, then the neutral ferrocenyl substituent was fixed in the 8-position by a Negishi cross-coupling reaction. The deprotonation of the cyclopentadienyl substituent, and the subsequent coordination of the half-sandwich fragments ML = [Fe(eta5-C5Me 5)]+, [Rh(eta5-C5Me 5)]2+, [Ir(eta5-C5Me 5)]2+, [Ru(eta6-C6H 6)]2+ to the cyclopentadienyl anion revealed the desired dinuclear complexes 1-[(eta5-cyclopentadienediyl)- (eta5-pentamethylcyclopentadienyl)iron(II)]-8- ferrocenylnaphthalene (5), 1-[(eta5-cyclopentadienediyl) (eta5-pentamethylcyclopentadienyl)rhodium(III)]-8- ferrocenylnaphthalene hexafluorophosphate (6PF6), 1-[(eta5-cyclopentadienediyl)(eta5- pentamethylcyclopentadienyl)iridium(III)]-8-ferrocenylnaphthalene hexafluorophosphate (7PF6), and 1-[(eta6-benzene) (eta5-cyclopentadienediyl)ruthenium(II)]-8-ferrocenylnaphthalene hexafluorophosphate (8PF6). The neutral complex 5 was oxidized to the paramagnetic cation 1-[(eta5-cyclopentadienediyl)- (eta5-pentamethylcyclopentadienyl)iron(III)]-8- ferrocenylnaphthalene hexafluorophosphate (5PF6). Compounds 3, 5PF6, 6PF6, and 7PF6 were characterized by X-ray structure determination; the neutral compound 3 crystallizes in the space group P21/c, whereas all of the cationic dinuclear complexes crystallize in the chiral space group C2221. A cyclic voltammetry study points to a predominant “through-space” interaction between the cationic sandwich unit and the neutral ferrocene substituent. The compounds 5PF6, 6PF6, 7PF6, and 8PF6 were subjected to hyper-Rayleigh scattering (HRS) and Kurtz-powder measurements. In both studies no SHG intensity could be observed.

Photoswitchable Arene Ruthenium Complexes Containing o-Sulfonamide Azobenzene Ligands

A series of arene ruthenium complexes containing o-sulfonamide azobenzene ligands were synthesized and found to exhibit uncommon coordination pattern with an exocyclic =N bond. Upon irradiation, these complexes cleanly undergo E ? Z photoisomerization followed by thermal Z ? E isomerization (upon resting in the dark) whose rate is dependent on the solvent, the nature of the arene group, the sulfonamide moiety, and azobenzene substitution, as revealed by structure-property studies.

Base-assisted cyclometalation and phosphorus-carbon bond cleavage in (arene)ruthenium(ii) complexes containing functionalized iminophosphorane- phosphine ligands Ph2PCH2P{=NP(=X)(OR)2}PH 2 (X = O, S; R = Et, Ph)

The bond-assisted cyclometalation and phosphorus-carbon bond cleavage in (Arene)ruthenium(II) complexes are discussed. The complexes contain functionalized iminophosphorane-phosphine ligands Ph2PCH 2P{=NP(=X)(OR)2}Ph2 (X = O, S; R = Et, Ph). It is found that the functionalized iminophosphorane-phosphines act as versatile ligands upon coordination to a (eta6-arene)-ruthenium(II) fragment. The results show that the ligands are used as templates for the construction and stabilization of unusual organometallic ruthenium(II) complexes.
