The Synthesis of Diethyl p-Tolylsulphonylethynylphosphonate and Related Acetylenes, and their Reactions with Nucleophiles, Pyridinium-1-dicyanomethylides, and Dienes

Diethyl p-tolylthioethynylphosphonate (10) was synthesized from diethyl ethynylphosphonate (7) by two routes and oxidized to the corresponding sulphoxide (11) and sulphone (12).The sulphone showed no triple bond i.r. absorption, but a strong Raman band, a
