Unusual metal-dependent acceleration and deceleration in the metal-catalyzed hydrosilylation of olefin using pyridyldimethylsilanes
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 reaction, huge rate deceleration was observed with 2-PyMe2SiH and 4-PyMe2SiH in the Pt-catalyzed reaction.
