摘要
Pd(OAc)(2)-catalyzed aerobic alkenylation and dienylation of ferrocene with electron-poor olefins and dienes (ethyl acrylate, methyl (E)-cinnamate, diethyl fumarate and maleate, ethyl sorbate and sorbic acid) is reported. In the case of acrylate and cinnamate the reaction leads to mixtures of mono-and dialkenylated ferrocenes. In other cases the products of mono alkenylation and dienylation are formed in low yield. The relatively slow (similar to 1 week) reaction takes place in AcOH solutions at room temperature.
