A synthon for a 14-electron Ir(III) species: catalyst for highly selective β-(Z) hydrosilylation of terminal alkynes.
نویسندگان
چکیده
A synthon for a 14-electron Ir(III) species is described. The geometrical control exerted by the ligand system over the Ir-alkenyl intermediate in hydrosilylation of terminal alkynes precludes formation of the more thermodynamically stable β-(E)-vinylsilane, thus affording the β-(Z) isomer in excellent yields.

An alternative mechanistic paradigm for the β-Z hydrosilylation of terminal alkynes: the role of acetone as a silane shuttle.
The β-Z selectivity in the hydrosilylation of terminal alkynes has been hitherto explained by introduction of isomerisation steps in classical mechanisms. DFT calculations and experimental observations on the system [M(I)2{κ-C,C,O,O-(bis-NHC)}]BF4 (M=Ir (3a), Rh (3b); bis-NHC=methylenebis(N-2-methoxyethyl)imidazole-2-ylidene) support a new mechanism, alternative to classical postulations, based...
متن کاملSBA-15-supported-dithizone-copper(I): An efficient heterogeneous catalyst for synthesis of 1,4-disubstituted 1,2,3-triazoles in water
In this work, the SBA-15-supported dithizone-copper(I) [SBA-15-dtz–Cu(I)] complex as a new heterogeneous catalyst is prepared for the first time. The catalyst prepared is characterized by the FT-IR spectroscopy, SEM, and ICP techniques. This reusable heterogeneous catalyst can be used in the click reactions for the green and facile synthesis of 1,4-disubstituted 1,2,3-triazolesvia a on...
متن کاملMn (III) salen complex supported on graphene oxide nanosheets as a highly selective and recoverable catalyst for the oxidation of sulfides
In this study, Mn (III) salen complex was synthesized and immobilized onto the graphene oxide, which is modified by 3-chloropropyltrimethoxy silane. Heterogeneous catalyst was characterized by X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, fourier transform infrared spectra, nitrogen adsorption−desorption isotherm and atomic absorption spectroscopy. The catalyt...

An efficient synthesis of chromenylphenylpropanone derivatives as warfarine-like analogues was developed by the Michael addition of 4-hydroxycoumarin to α,β-unsaturated compounds in the presence of polyvinylpolypyrrolidone supported antimony(III) chloride (PVPP-SbCl3) as a new polymeric Lewis acid catalyst in chloroform at reflux conditions without formation of 2,4-...
متن کاملPreparation of Ag2S Nanoparticles and using as Catalyst for the A3-coupling (Aldehyde-Amine-Alkyne) Reaction
Microwave assisted facile one-step approach was adopted to prepare mono-dispersed silver sulfide nanoparticles. The structures of the synthesized Ag2S nanoparticles were confirmed by Fourier-transform infrared spectroscopy (FT-IR), diffuse reflectance UV-vis spectroscopy (DRS), X-ray diffractometer (XRD), energy dispersive X-ray analysis (EDX) and transmission electron microscope (TEM). The pre...
