, p. 367 - 368 (1984)
Molybdenum(II) acetate dimer or titanium(IV) i-propoxide induced regiospecific ring cleavage of α,β-epoxysilanes to form the enolate intermediates, which reacted with aldehydes to give the corresponding α,β-unsaturated carbonyl compounds.
OXIDATION OF ALDEHYDES TO α,β-UNSATURATED ALDEHYDES VIA α-CHLOROALDIMINES
Kimpe, Norbert De,Stevens, Christian
, p. 41 - 46 (2007/10/02)
The oxidation of aldehydes to α,β-unsaturated aldehydes has been performed by a sequence of reactions involving conversion into aldimines, chlorination at the α-position to form α-chloroaldimines, base-induced dehydrochlorination and hydrolysis.The four-step transformation can be executed without isolation of the intermediates.This method has been applied to the synthesis of an artificial flavor, i.e. 2-butyl-3-phenylpropenal.
REACTION OF ENOLATES OF ACYLTRIMETHYLSILANES WITH ALDEHYDES. CANNIZZARO TYPE OXIDATION-REDUCTION REACTION WITH A TRIMETHYLSILYLCARBONYL GROUP

, p. 525 - 528 (2007/10/02)
The reaction of an acyltrimethylsilane enolate with 2 eq of an aldehyde gives a 1:2 adduct, while that with the enolate of an α-chloroacyltrimethylsilane affords an α,β-unsaturated aldehyde as a 1:1 adduct accompanied by the carboxylic acid derived from the starting aldehyde.An oxidation-reduction reaction mechanism on the trimethylsilylcarbonyl group has been proposed.
