Abstract
When α‐acetylenic alcohols are reacted with acid chlorides of trivalent phosphorus in the presence of a tertiary base, the intermediate trivalent esters rearrange to pentavalent phosphorus derivatives, with formation of a new PC bond. Generally, the C3 group fixed on the phosphors has an allenic structure: ; in some cases this group tautomerizes to the corresponding acetylenic derivative: .Keywords
