Etherification of alkoxydialkylsilanes with carbonyl compounds

Jiang, Xinglong,Bajwa, Joginder S,Slade, Joel,Prasad, Kapa,Repi?, Oljan,Blacklock, Thomas J

, p. 9225 - 9227 (2002)

A novel method for preparing ethers from alkoxydialkylsilanes and carbonyl compounds through reductive etherification is described. The salient feature in this method is the utilization of internal hydrogen as the hydride source for reducing the oxonium intermediate generated by using the Cl(R)2SiBr[BiBr3/Cl(R)2SiH] catalytic system.
