Abstract Since the review of Yorimitsu and Oshima in 2010, past 15 years have witnessed significant progresses application 1‐alkynylphosphorus compounds organic synthesis. Owing to reactive carbon‐carbon triple bond association with electron‐withdrawing phosphoryl group, they easily undergo transition metal‐catalyzed nucleophilic addition reactions at β‐position carbon‐ heteroatom‐based nucleophiles afford structurally diverse 1‐alkenyl phosphorus compounds. Especially, when 1‐alkynylphosphonates or phosphinates are used, intramolecular substitution on P‐atom might occur some cases, which would result formation P ‐based heterocycles. In addition, existing makes them prone go through reaction initiated cyclization [2+2], [2+3], [2+4], [2+5] [2+2+2] cycloaddition other unsaturated bonds, provides an efficient access various heterocycles phosphorylated
