dc.description.abstract | Cationic rhodium(I) complexes containing picolyl-NHC
(NHC = N-heterocyclic carbene) ligands that differ in the substitution at
the 6-position of the pyridine donor serve as efficient E-selective alkyne
hydrosilylation catalyst precursors. Particularly, when the steric
hindrance of the picolyl fragment is increased, a catalyst precursor
exhibiting high catalytic activities (TOF up to 500 h−1 at S/C ratios of
1000) and excellent E selectivities (E/α ratio ≥95/5) in the
hydrosilylation of a series of aryl, alkyl, and functionalized terminal
alkynes with both carbo- and alkoxysilanes has been obtained. The
picolyl-NHC ligands in the Rh complexes exhibit a dynamic behavior in
solution due to the hemilabile coordination of the pyridine fragment.
Preliminary mechanistic studies support the involvement of Rh silyl hydrido species, which are generated in low concentrations
from Rh complexes and the silane, in the hydrosilylation of alkynes in agreement with the assumption of Chalk−Harrod-type
mechanisms. | es |
