A Cr-catalyzed enantioconvergent allenylation reaction of aldehydes with racemic propargyl halides has been developed. This robust method employs simple and readily accessible materials, exhibits exceptional functional group tolerance and broad substrate scope, and provides facile access to a wide range of valuable optically enriched α-allenols with two or three continuous chiral centers, including
