K. Itami et al., Unusual metal-dependent acceleration and deceleration in the metal-catalyzed hydrosilylation of olefin using pyridyldimethylsilanes, CHEM LETT, (11), 2001, pp. 1088-1089
The Rh- and Pt-catalyzed hydrosilylations of olefin utilizing 2-pyridyl-, 3
-pyridyl-, 4-pyridyl-, and phenyldimethylsilane are described. Whereas huge
rate acceleration was observed with 2-PyMe2SiH in the Ph-catalyzed reactio
n, huge rate deceleration was observed with 2-PyMe2SiH and 4-PyMe2SiH in th
e Pt-catalyzed reaction.
