The reaction of tributyltinenolates, prepared from tributyltin methoxide and enol acetates in situ, with 1-bromo-1-alkenes in the presence of a catalytic amount of PdCl2(o-tolyl3P)2 was found to give the derivatives of allyl ketone in good yields.
Palladium catalyzed reaction of acyltins with organichalides were investigated. Among the halides, acyl halides and allylic halides were good substrates, and the latter gave allylic ketones in good yields.
