Benzyl alcohol 1a was reacted with 1.25 equivalents of phenylphosphonyl dichloride (PPDC; PhP(O)Cl2) in the presence of triethylamine (Et3N) to afford a mixture of mono- and bis-phosphates. The monosubstituted product was reacted directly with p-cresol without purification to afford the desired phenylphosphonate 2a.

Carbodiimide 1 reacts with acyl chloride 3 to generate N-acylimide salt 5. Alkyne 2 is immediately converted to acetylide copper 4 in the presence of triethylamine, and 1 equivalent of triethylamine acid salt is released. Subsequently, 4 undergoes nucleophilic attack on 5 to obtain the target product 6, and the copper catalyst is released, completing the catalytic cycle.
