Frustrated lewis pair route to hydrodesilylation of silylphosphines

A 1:1 mixture of P(SiMe3)3 and B(p-C 6F4H)3 reacts with 3 equiv of 4-heptanone to afford a 1:2 mixture of [(Me3SiO)(n-Pr)2C]H 2P-B(p-C6F4H)3 and the silyl enol ether, 4-trimethylsiloxy-3-heptene. Subsequent thermolysis of the adduct produces H3P-B(p-C6F4H)3 and an additional equiv of silyl enol ether. In the presence of a catalytic quantity of B(p-C6F4H)3, however, P(SiMe3) 3 reacts with 4-heptanone to produce a 1:1 mixture of [(Me 3SiO)(n-Pr)2C]2PH and silyl enol ether. Heating this mixture further produces [(Me3SiO)(n-Pr)2C]PH 2, which is eventually converted to elemental phosphorus.

Azilidine-Trimethylsilyl Bromide-Ph4SbBr System as a Novel Selective Reagent for Synthesis of Silyl Enol Ethers from Cyclic Ketones

Azilidine-trimethylsilyl bromide-tetraphenylstibonium bromide system is an effective reagent to produce silyl enol ethers from cyclic ketones.This had the specific selectivity to silylate cyclic ketones exclusively even in the case of coexsisting with acyclic ketones.
