Palladium-Catalyzed Ethoxycarbonylation of Arenediazonium Tetrafluoroborates
Abstract:
Palladium-catalyzed ethoxycarbonylation reaction of arenediazonium tetrafluoroborates has been carried out under very mild conditions in the presence of a catalytic amount of Pd(OAc)2 and CaO to afford a variety of substituted ethyl benzoates in good yields. The effects of the catalyst and the base on ethoxycarbonylation reaction were investigated and CaO was shown to be the best base. The ethoxycarbonylation reaction can tolerate a variety of substituents in the benzene rings and has very high chemoselectivity. This paper provides a simple and practical procedure for syntheses of a variety of substituted ethyl benzoates.
