Abstract

Abstract: The selective activation/functionalization of benzhydryl CACHTUNGTRENNUNG (sp3) ÀH bonds is documented. The gold complex XPhosAuNTf2 turned out to be an efficient catalyst (5 mol%) to transform readily available propargylic esters into di-or trisubstituted naphthalenes in high yield. A 1, 5-hydride shift is postulated as the key step of the cascade reaction sequence. Keywords: CÀH functionalization; gold catalysis; 1, 5- ...
