Activation of carbon dioxide and carbon disulfide by a scandium N-heterocyclic carbene complex.
نویسندگان
چکیده
A Sc NHC complex readily activates three equivalents of CO2 showing 'Frustrated Lewis Pair' type reactivity with each metal-carbene bond, but whilst CS2 is also activated by the labile carbenes, no metal involvement is observed.

The chiral N-heterocyclic carbene-catalyzed [2+2+2] cycloaddition of ketenes and carbon disulfide was realized to give the cycloadduct of 1,3-oxathian-6-ones in good yields with excellent enantioselectivities.
متن کاملHighly efficient catalytic hydrosilylation of carbon dioxide by an N-heterocyclic carbene copper catalyst.
The N-heterocyclic carbene-copper alkoxide complex [(IPr)Cu(OtBu)] acts as a highly efficient catalyst for the hydrosilylation of carbon dioxide with a hydrosilane. The desired product, silyl formate could be isolated in multigram quantity under solvent free conditions. A copper formate catalyst intermediate was successfully isolated and structurally characterized, thus offering important insig...

The reactions of f-block silylamido N-heterocyclic carbene (NHC) complexes ([M(L)(N{SiMe(3)}(2))(2)], M = Y, Ce, and U, L = bidentate alkoxy-tethered NHC ligand) with CO and CO(2) have been studied and compared to each other, to those of selected [M(L)(2)(N{SiMe(3)}(2))] complexes, and to those of [M(N{SiMe(3)}(2))(3)] to identify the effect of the labile NHC group on the small molecule activat...
متن کاملCatalytic boracarboxylation of alkynes with diborane and carbon dioxide by an N-heterocyclic carbene copper catalyst.
By the use of an N-heterocyclic carbene copper(I) complex as a catalyst, the boracarboxylation of various alkynes (e.g., diaryl alkynes, aryl/alkyl alkynes, and phenylacetylene) with a diborane compound and carbon dioxide has been achieved for the first time, affording the α,β-unsaturated β-boralactone derivatives regio- and stereoselectively via a borylcupration/carboxylation cascade. Some imp...
متن کاملTheoretical Study of Addition Reaction of Carbene and Zigzag Single-walled Carbon Nanotube
The reaction mechanism between (H2C) and (7, 0), zigzag single-walled carbon nanotubes(ZSWCNTs) on two different orientation of C-C have been studied by semi empirical AM!method. The activation barriers of (H2C) adding to (7, 0) ZSWCNT are computed and compared.The effects of diameters of zigzag SWCNT on their binding energies were studied
