A Ru(ii)-catalyzed coupling of various α-carbonyl phosphoniums with sulfoxonium ylides has been realized for the facile synthesis of 1-naphthols in good to excellent yields. This oxidant-free transformation proceeds through Ru-catalyzed C-H activation of phosphoniums, Ru-carbene insertion, and intramolecular Wittig reaction processes.

(Chemical Equation Presented) Twice expanded: Substituted naphthols were prepared in a novel synthetic route starting from alkenyl benzocyclobutenol derivatives. The conversion includes two successive ring-enlargement processes (A→B→C; see scheme). The ha
