A Ru(ii)-catalyzed coupling reaction has been developed for the synthesis of 1-naphthols in good to excellent yields. The transformation proceeds through Ru-catalyzed C-H activation of phosphoniums, Ru-carbene insertion, and intramolecular Wittig reaction processes.
A Ru(ii)-catalyzed coupling of various alpha-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.
