Base-Free Direct Synthesis of Alkynylphosphonates from Alkynes and H-Phosphonates Catalyzed by Cu2O

A simple and mild methodology for the direct synthesis of alkynylphosphonates is presented. The reaction of a variety of terminal alkynes with dialkyl phosphites in the presence Cu2O (14 mol %) led to the formation of the corresponding alkynylp

Synthetic method of alkynyl phosphate

The invention provides a synthetic method of alkynyl phosphate. The synthetic method comprises the steps of dissolving alkyne, hydrogen phosphonate and a photocatalyst into an organic solvent to obtain a mixed solution, adding a catalytic amount of copper
