A series of β,γ-unsaturated ketones were isomerized to their corresponding α,β-unsaturated ketones by the introduction of DABCO in iPrOH at room temperature. The endo-cyclic double bond (β,γ-position) on ketone was rearranged to exo-cyclic double bond (α,β-position) under the reaction conditions.
Acylation du (cyclopropylmethyl)trimethylsilane. Une nouvelle voie d'acces aux enones non conjuguees

Acylation of (cyclopropylmethyl)trimethylsilane using RCOCl/AlCl3 (R: saturated hydrocarbon group) constitutes a mild, convenient route to β,γ-unsaturated ketones free from the conjugated isomers.With α,β-unsaturated acyl chlorides a competitive reaction between the C-H and C-Si allylic cleavage is observed whereas chloroacetyl chloride affords the γ,δ-ethylenic corresponding ketone.A mechanism involving the catalytic role of HCl in the formation of β,γ-unsaturated and chloroketones is proposed.
SYNTHESE STEREOSPECIFIQUE DE BUTENYL-2 CETONES ET DE L'ACIDE BUTENE-2 SULFONIQUE

, p. 2883 - 2884 (2007/10/02)
1-Trimethylsilyl 2-methylcyclopropane cis or trans resulting from the silylation of 1-bromo 1-propene is a convenient regio- and stereospecific precursor of β,γ-unsaturated Z or E ketones and 2-butene sulfonic acid.
