Synthesis of allene triazole through iron catalyzed regioselective addition to propargyl alcohols

Allene triazole derivatives were successfully synthesized for the first time through iron catalyzed regioselective triazole addition to tertiary propargyl alcohols. The reaction proceeds under mild conditions, giving the desired allene-triazoles in good to excellent yields (up to 96%). The resulting allene-triazoles were confirmed by X-ray crystallography and indicated improved stability.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: Cl3Ru, you can also check out more blogs about10049-08-8

The synthesis of an anionic, tetraphenylborate-functionalized, [P,N]-hybrid phosphinobenzimidazole ligand and its hemilabile behaviour in ruthenium zwitterion chemistry

A new anionic [P,N]-hybrid ligand based on a phosphinobenzimidazole scaffold and functionalized with a tetraphenylborate substituent is reported. This new anionic ligand readily chelates to a variety of ruthenium- cyclopentadienyl and -pentamethylcyclopentadienyl precursors to form a series of zwitterionic ruthenium piano-stool complexes (eta5-C 5R5)Ru(L)(kappa2-P,N) (R = H or Me; L = CO or PPh3). In the presence of excess CO or 1-alkynes, the chelate complexes undergo ring-opening of the kappa2-P,N ligand at the ruthenium-nitrogen bond (in some cases reversibly) under relatively mild conditions. In particular, the reactions with 1-alkynes proceed via vinylidene intermediates which subsequently insert into the ruthenium-nitrogen bond of the kappa2-P,N ligand.

Highly Selective Olefin Metathesis with CAAC-Containing Ruthenium Benzylidenes

Several olefin metathesis reactions are studied, namely, jojoba oil oligomerization, methyl oleate self-metathesis, ring-closing metathesis (RCM) to form a nitrogen heterocycle, and 1,5-hexadiene acyclic diene metathesis polymerization (ADMET). The catalyst containing the Bertrand-Grubbs cyclic alkyl amino carbene (CAAC) ligand showed high selectivity by diminishing isomerization reactions; this was especially clear at high temperatures where the more widely used nitrogen heterocyclic carbene (NHC)-based catalysts show side reactions. Experimental and computational studies determined that it is much more difficult to produce ruthenium hydrides with CAAC, a property that can explain the improved observed activity. This finding opens a pathway for the development of even more selective olefin metathesis catalysts for reactions that require harsh conditions.

Gold-catalyzed intramolecular allylation of silyl alkynes induced by silane alcoholysis

The activation of alkynyl allyl silanes with a cationic gold catalyst in the presence of alcohols provides vinyl silanes that contain the allyl group at the beta-position and the alkoxysilyl group in cis-orientation. The bond reorganization process is most consistent with the involvement of a carbocationic intermediate, which undergoes a nucleophilic attack by an alcohol selectively at the silicon center. The cis-vinyl silyl ether products can be further elaborated by ring-closing and cross metathesis to form more substituted 1,4-dienyl silanes. Copyright

Preparation and redox studies of alpha1- and alpha2-isomers of mono-Ru-substituted dawson-type phosphotungstates with a DMSO Ligand: [alpha1/alpha2-P 2W17O61RuII(DMSO)]8-

Both alpha1- and alpha2-isomers of mono-Ru-substituted Dawson-type heteropolytungstates with a DMSO ligand, [alpha1-P2W17O61Ru II(DMSO)]8- and [alpha2-P2W 17O61RuII(DMSO)]8-, are prepared from the alpha2-isomer of a monolacunary derivative, [alpha2-P2W17O61]10-. Reaction of [alpha2-P2W17O61] 10- with Ru(DMSO)4Cl2 under hydrothermal conditions produces [alpha2-P2W17O 61RuII(DMSO)]8- as a main product together with [alpha1-P2W17O61Ru II(DMSO)]8-, [PW11O39Ru II(DMSO)]5-, and [P2W18O 62]6- as byproducts. By addition of KCl to the reaction mixture, K8[alpha2-P2W17O 61RuII(DMSO)] is isolated in a moderate yield. On the other hand, reaction of [alpha2-P2W17O 61]10- with Ru2(benzene)2Cl 4 under hydrothermal conditions produces an isomeric mixture of [P2W17O61RuIII(H2O)] 7- (alpha1-isomer/alpha2-isomer ratio: ca. 8/1) as a main product together with [PW11O39Ru III(H2O)]4- and [P2W 18O62]6- as byproducts. By addition of acetone to the reaction mixture, K7[P2W17O 61RuIII(H2O)] is isolated in a good yield. Reaction of [P2W17O61RuIII(H 2O)]7- with DMSO produces [alpha1-P 2W17O61RuIII(DMSO)]7- as a main product and [alpha2-P2W17O 61RuIII(DMSO)]7- as a minor product. By addition of KCl and acetone, the alpha1-isomer K 8[alpha1-P2W17O 61RuII(DMSO)] is isolated in a good yield. Both compounds are fully analyzed by CV, NMR (1H, 13C, 31P, and 183W), IR, UV-vis, elemental analysis, mass spectroscopy, and single-crystal structure analysis. Assuming that isomerization does not occur during the reaction of [P2W17O61Ru III(H2O)]7- with DMSO, the isolated [P 2W17O61RuIII(H2O)] 7- contains the alpha1-isomer as a main compound with the alpha2-isomer as a minor compound. Unusual transformation of the alpha2-isomer of [P2W17O 61]10- to the alpha1-isomer occurs. Redox behaviors of [alpha1-P2W17O 61RuII(DMSO)]8- and [alpha2-P 2W17O61RuII(DMSO)]8- are compared together with Ru(DMSO)-substituted alpha-Keggin-type heteropolytungstates, [alpha-XW11O39Ru(DMSO)] n- (X = Si, Ge, and P).

Switching and extension of a [c2]daisy-chain dimer polymer

(Chemical Equation Presented) We report the synthesis of a [c2]daisy-chain dimer via ruthenium-catalyzed ring-closing olefin metathesis. Confirmation of the interlocked nature of the structure was achieved through single-crystal X-ray diffraction analysis. The dimer could be readily switched from the bound to the unbound conformation by treatment with 3.0 equiv of KOH and subsequently reprotonated by treatment with 3.0 equiv of HPF6. Azide functionalization of the dimer enabled incorporation in linear step-growth polymer chains using the alkyne-azide “click” reaction. Gel permeation chromatography coupled with multiangle laser light scattering analysis showed the polymers contained 22 dimers and had a radius of gyration of 14.8 nm. Acylation of the amines of the dimers sterically forced elongation of the interlocked units, and MALLS analysis of the polymer showed a 48% increase in the Rg (21.4 nm).
