摘要

Abstract A convenient synthesis of α, β-unsaturated esters (in 68–96% yields) from the reaction of a bromomalonic ester with aldehydes promoted by tri-n-butylarsine is described. A mechanism involving halophilic attack of tri-n-butylarsine leading to the formation of a salt followed by reaction with carbonyl compounds is proposed. This methodology provides a convenient route to α, β-unsaturated esters and represents an alternative to the ...
