One‐Carbon Homologation of Primary Alcohols and the Reductive Homologation of Aldehydes Involving a Jocic‐Type Reaction

Abstract (Trichloromethyl)carbinols, which are formed in one operation from either alcohols or aldehydes, can be converted into primary alcohols in a Jocic‐type reaction involving LiBH 4 . The net result is a convenient two‐step, one‐carbon homologation of primary alcohols or a reductive one‐carbon homologation of aldehydes featuring a broad substrate scope. The method is step‐economical, and it nicely complements established one‐carbon homologation strategies.
