Ruthenium-catalyzed dealkenative N-silylation of amines by substituted vinylsilanes.
The ruthenium hydride complex-catalyzed N-silylation of primary and secondary amines with substituted vinylsilanes, with the general formula R(1)CH=CHSiR (where R(1) = H, Ph, n-Bu, Si(OEt)3), leading to the formation of a Si-N bond with the evolution of olefin is described. Vinylsilane acts as a silylative reagent and hydrogen acceptor. Under optimum conditions, the reaction offers an attractiv...

Synlett 2002, No. 12, Print: 02 12 2002. Art Id.1437-2096,E;2002,0,12,1954,1965,ftx,en;A30202ST.pdf. © Georg Thieme Verlag Stuttgart · New York ISSN 0936-5214 Abstract: Two different synthetic reactions catalyzed by an iridium complex are discussed. The first is allylic alkylation and allylic amination. This reaction proceeds via a -allyl iridium intermediate. The selectivity strongly depends o...
متن کاملOne-pot synthesis of alcohols from olefins catalyzed by rhodium and ruthenium complexes
The one-pot synthesis of butanol and heptanol from propene and 1-hexene, respectively, was performed using Ru3(PPh3)Cl2 and Rh(CO)2(acac) in the presence of triphenylphosphene. The effects of various reaction parameters, including catalyst concentration, gas partial pressures, and temperature, were investigated. Two methods for performing the one-pot synthesis were developed and are discussed. ...
متن کاملRuthenium-catalyzed ring-closing metathesis to form tetrasubstituted olefins.
[structure: see text]. Increased efficiency for ring-closing metathesis to form tetrasubstituted olefins using N-heterocyclic carbene ligated ruthenium catalysts was achieved by reducing the size of the substituents at the ortho positions of the N-bound aryl rings.
متن کاملRuthenium catalyzed selective hydrosilylation of aldehydes.
A chemoselective hydrosilylation method for aldehydes is developed using a ruthenium catalyst [(Ru(p-cymene)Cl2)2] and triethylsilane; a mono hydride bridged dinuclear complex [{(η(6)-p-cymene)RuCl}2(μ-H-μ-Cl)] and a Ru(iv) mononuclear dihydride complex [(η(6)-p-cymene)Ru(H)2(SiEt3)2] are identified as potential intermediates in the reaction and the proposed catalytic cycle involves a 1,3-hydri...
