greatly increased when the dimes are heated in the presence of 1,3-dienes. The major products are 3-phospholenes and 3a, 7a-dihydrophosphindoles, formed in retrocycloaddition of the P(V) adduct of the diene and the phosphine.

Under thermal conditions where intermolecular interactions are minimized, as in flashvacuumpyrolysis, the diphosphines derived from deoxygenation of P-methylphosphole oxide dimers are excellent sources of P-methylphospholes.
