2-Aza-1,3-butadienes have been synthesized from carbonyl compounds and 1,1,1,3,3,3-hexamethyl-disilazane in the presence of cobalt-containing catalysts. The best yields (up to 95%) were achieved in the case of aldehydes branched in the α-position and 2-methylcyclohexanone. In the case of two α,β-unsaturated ketones, pyridine derivatives were found as the main products. Copyright Taylor & Francis Group, LLC.
A novel synthesis of silyl enol ethers from α-silylbenzylthiols and carboxylic acid derivatives via C-C bond formation; thermal rearrangement of S-α-silylbenzyl thioesters

A new procedure for the synthesis of silyl enol ethers from S-α-silylbenzyl thioesters without need for either bases or catalysts via C-C bond formation is described. Solutions of S-α-silylbenzyl thioesters were simply heated at 180°C for 24 h in a sealed tube to give silyl enol ethers in good yields with high stereoselectivity. Cyclization of the dipoles generated by thermal rearrangement of the silyl group and elimination of sulfur afforded silyl enol ethers.
HIGHLY SELECTIVE, KINETICALLY CONTROLLED ENOLATE FORMATION USING LITHIUM DIALKYLAMIDES IN THE PRESENCE OF TRIMETHYLCHLOROSILANE
Corey, E. J.,Gross, Andrew W.
, p. 495 - 498 (2007/10/02)
The deprotonation of ketones and esters with lithium dialkylamides in the presence of trimethylchlorosilane leads to enhanced selectivity for the kinetically generated enolate.Lithium t-octyl-t-butylamide is shown to be superior to lithium diisopropylamid
