AbstractThe selective activation/functionalization of benzhydryl C(sp3)H 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.magnified image
