Novel synthesis of .alpha.,.beta.-unsaturated ketones by the palladium-catalyzed arylation of ketenes with aroyl chlorides or the decarbonylative cross-condensation of acyl halides
α,β-Unsaturated ketones were obtained from alkylphenylketene and aroyl chloride via decarbonylation reaction in the presence of catalytic amounts of tetrakis(triphenylphosphine) palladium.
在催化量的四(三苯基膦)钯存在下,通过脱羰反应从烷基苯乙烯酮和芳酰氯获得α,β-不饱和酮。
Palladium-catalysed decarbonylative cross condensation of acyl halides
The reaction of alkylphenylacetyl chlorides with aroyl chlorides catalysed by tetrakis(triphenylphosphine)palladium gives α,β-unsaturated ketones selectively via a decarbonylativecrosscondensation reaction.
