Abstract

Abstract A concise method for the preparation of 1-acyl-4-alkoxy-or 1-acyl-4- alkylsulfanylnaphthalenes has been developed by the PtCl 2-catalyzed reaction of o- ethynylbenzoates or benzothioates with vinyl ethers. Treatment of o-alkynylbenzoate derivatives with PtCl 2 generated the platinum (II)-containing carbonyl ylides as a key reactive intermediate and these species reacted with vinyl ethers to give substituted ...
