✦ Synopsis

Enol acetates derived from saturated ketones are converted to a,&unsaturated ketones by heating with ally1 methyl carbonate in MeCN by bimetallic catalysis of palladiumphosphine complex and tin methoxide. Conversion of saturated ketones to corresponding a,&unsaturated ketones is an important synthetic method. Established methods are based on introduction of hetero atoms (Cl, Br, S, Se) at the o-position, and their elimination with B-hydrogen. 1,233) We have reported before
