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.
REGIOSELECTIVE PREPARATION OF KINETIC TRIMETHYLSILYL ENOL ETHERS FROM β-KETO SILANES
Yamamoto, Yohsuke,Ohdoi, Keisuke,Nakatani, Masayuki,Akiba, Kin-ya
, p. 1967 - 1968 (2007/10/02)
Kinetic trimethylsilyl enol ethers were prepared regioselectively by the two-step method, i.e., trimethylsilyl triflate catalyzed rearrangement of β-keto silanes which were prepared from trimethylsilylmethylcopper and acid chlorides.
