Abstract

A convenient and generalizable procedure has been optimized to access to 1-hydroxymethylene-1,1-bisphosphinate compounds. Several alkyl, including an alendronate bisphosphinate analog, and (hetero)aryl compounds were rapidly obtained in satisfying to excellent yields. A side product could be identified as a phosphino-phosphonate isomer and plausible mechanistic pathways are discussed here.
