Reactions of 1-ethyl-1,2-diphosphole with acetylenes

The cycloaddition of 1-ethyl-3,4,5-triphenyl-1,2-diphosphacyclopenta-2,4-diene to acetylenes R 1 C≡CR 2 (R 1 = R 2 = CO 2 Me; R 1 = Ph, R 2 = H) gives phosphinine along with oligomeric products. In the case of nonsymmetric phenylacetylene, the process is regioselective.
