The syntheses and characterisations of 1,2-Ph2-3-(eta-C5Me 5)-3,1,2-pseudocloso-IrC2B9H9 1, 1,2-Ph2-3-(eta-C6H 6)-3,1,2-pseudocloso-RuC2B9H9 2, 1,2-Ph2-3-(cym)-3,1,2-pseudocloso-RuC2B9H 9 (cym = p-cymene) 3 and 1,2-Ph2-3-(eta-C6Me 6)-3,1,2-pseudocloso-RuC2B9H9 4 are reported from the reactions between Tl2[7,8-Ph2-nido-7,8-C2B9H 9] and either [{IrCl2(C5Me5)}2] or the appropriate [{RuCl2(arene)}2] species. By 11B NMR spectroscopy all these compounds have pseudocloso geometries, in which the C(1) … C(2) connectivity is broken and an approximately square M(3)C(1)B(6)C(2) face is generated. Crystallographic studies on 2 and 3 confirm this suggestion. It is suggested that distortion in these species arises from steric crowding between the Cphenyl substituents, forced to adopt conformations with high theta values by the presence of the eta-bonded substituent at M(3). Individual gauge for localised orbitals calculations, reported for the first time on transition-metal heteroboranes, reasonably reproduce the (previously assigned) 11B NMR chemical shifts of 3-(eta-C5Me5)-3,1,2-closo-RhC2B 9H11, and allow a tentative assignment of those of 1,2-Ph2-3-(eta-C5Me 5)-3,1,2-pseudocloso-RhC2B9H9.

The synthesis of new chiral N-monotosylated-1,2-diamines based on the (-)-menthol skeleton is presented. The elimination of HCl from neomenthyl chloride obtained from an Appel reaction led to p-menth-3-ene in excellent yield. Further functionalization of the double bond in p-menth-3-ene with chloramine-T gave the corresponding N-tosylaziridines, which upon reaction with sodium azide and subsequent reduction of the azide functional group, formed the 1,2-diamine system. The synthesized chiral ligands proved effective in the asymmetric transfer hydrogenation of aromatic ketones and an endocyclic imine.

Carbohydrates are integral to biological signaling networks and cell-cell interactions, yet the detection of discrete carbohydrate-lectin interactions remains difficult since binding is generally weak. A strategy to overcome this problem is to create multivalent sensors, where the avidity rather than the affinity of the interaction is important. Here we describe the development of a series of multivalent sensors that self-assemble via hydrophobic supramolecular interactions. The multivalent sensors are comprised of a fluorescent ruthenium(II) core surrounded by a heptamannosylated beta-cyclodextrin scaffold. Two additional series of complexes were synthesized as proof-of-principle for supramolecular self-assembly, the fluorescent core alone and the core plus beta-cyclodextrin. Spectroscopic analyses confirmed that the three mannosylated sensors displayed 14, 28, and 42 sugar units, respectively. Each complex adopted original and unique spatial arrangements. The sensors were used to investigate the influence of carbohydrate spatial arrangement and clustering on the mechanistic and qualitative properties of lectin binding. Simple visualization of binding between a fluorescent, multivalent mannose complex and the Escherichia coli strain ORN178 that possesses mannose-specific receptor sites illustrates the potential for these complexes as biosensors.

Ruthenium complexes of formula [(eta6-arene)Ru(LL*)- (H2O)][SbF6]2 (arene = C6H 6, p-MeC6H4iPr, C6Me6; LL* = bidentate chelate chiral ligand with PN, PP or NN donor atoms) have been tested as catalyst precursors for the asymmetric 1,3-dipolar cycloaddition of nitrones to methacrolein. The reaction occurs quantitatively with perfect endo selectivity and moderate enantioselectivity (up to 74 % ee). The ruthenium aqua complexes can be prepared from the corresponding chlorides, [(eta6-arene)RuCl(LL*)][SbF6]. Dipolarophile intermediates [(eta6-arene)Ru(PNiPr)(methacrolein)][SbF 6]2 (PNiPr = (4S)-2-(2-diphenylphosphanylphenyl)-4- isopropyl-1,3-oxazoline) as well as nitrone-containing complexes [(p-Me-C 6H4iPr)Ru(PNiPr)(nitrone)][SbF6]2 (nitrone = N-benzylidenephenylamine N-oxide, N-benzylidenemethylamine N-oxide, 3,4-dihydroisoquinoline N-oxide) have been also isolated and characterised.

(Chemical Equation Presented) Lock it in: A temporary silicon-based configurational lock (see scheme) has enabled an efficient and fully diastereo-selective assembly of the spiroketal subunit of spirofungin A. This complex natural product was synthesized in 20 steps, including a rapid polyketide assembly based on the ring-opening metathesis of a cyclopropenone acetal. It was established that spirofungin A elicited notable anti-proliferative activity against several human cancer cell lines and selectively inhibited isoleucyl-tRNA synthetase in vitro.

Dinuclear dichloro complexes [Ru(C6H6)Cl 2]2, [Ru(p-MeC6H4 iPr)Cl2]2, [Ru(1,2,4,5-C6H 2Me4)Cl2]2, and [Ru(C 6Me6)Cl2]2 react in ethanol with p-bromothiophenol to give the corresponding cationic complexes [Ru 2(C6H6)2(p-S-C6H 4-Br)3]+ (1), [Ru2(p-MeC 6H4iPr)2(p-S-C6H 4-Br)3]+ (2), [Ru2(1,2,4,5-C 6H2Me4)2(p-S-C6H 4-Br)3]+ (3), and [Ru2(C 6Me6)2(p-S-C6H4-Br) 3]+ (4), which can be isolated in quantitative yield as their chloride salts. X-ray structure analysis of these complexes shows that the nature of the arene ligand influences the folding of the p-S-C 6H4-Br units. In 1, where the less hindered arene ligand is present, the three phenyl rings of the thiolato units are not constrained to a coplanar arrangement, whereas in 4 the C6Me6 forces the three phenyl rings to be in perfect planarity. Complexes 2 and 3 show an intermediary arrangement.

The synthesis of polyaryl phosphonium salts by cyclotrimerization of aryl alkynes is induced by a stoichiometric amount of the ruthenium eta5-pentadienyl complex (eta5-C5H7)(PPh3)2RuCl (1). With only 1 mol % quantity, complex 1 efficiently catalyzed the dimerization of aryl alkynes at room temperature to afford the corresponding (Z)-1,4-diarylbut-1-en-3-yne derivatives as the major products.

The new dye complex bis[4,4?-di(2-(3-methoxyphenyl)ethenyl)-2, 2?-bipyridine][4,4?-dicarboxy-2,2?-bipyridine]-ruthenium(II) dihexafluorophosphate (1) has been prepared, characterised by absorption spectroscopy and adsorbed onto nanocrystalline TiO2 electrodes. The resulting system was studied by absorption spectroscopy, electrochemistry and photoelectrochemistry and the results were compared to those for a reference system with bis[2,2?-bipyridine]-[4,4?-dicarboxy-2,2?- bipyridine]ruthenium(II) (2). The system with 1 displays a broader and red-shifted UV-vis absorption compared to that with 2. Moreover, the system with 1 is less sensitive towards the water content in the electrolyte, and an adsorbed monolayer of 1 remains on the electrode surface after days even in aqueous NaOH (0.1 M), while 2 desorbs immediately.

A set of molecular triads was synthesized in which terminal ruthenium(II) and osmium (II) tris(2,2′-bipyridyl) fragments were separated by a butadiynylene residue bearing a central aromatic nucleus. The aromatic groups (1,4-phenylene, 1,4-naphthalene, and 9,10-anthracene) significantly influenced the nature of intramolecular triplet energy-transfer processes involving the terminals. Electron exchange occurred via superexchange interactions with the central phenylene group acting as mediator. The triplet energy of the connector decreased after replacing phenylene with naphthalene, such that the naphthalene-like triplet lies at slightly lower energy than the Ru(bpy) fragment but higher than the triplet state localized on the Os(bpy) unit. Triplet energy transfer along molecular axis entailed two discrete steps, forming the naphthalene-like triplet as a real intermediate, both of which were fast. The triplet energy of the anthracene-derived connector, which was lower than that of the Os(bpy) fragment, acted as an energy sink for photons absorbed by the terminal metal complexes. There was a slow energy leakage from the anthracene-like triplet to the Os(bpy) unit, which stabilized the latter triplet state, and provided a way for obtaining energy transfer along the molecular axis.
