The reaction of lithium 3,4-dimethyl-phospholide with tetrachloroethylene gives the corresponding 1,2-bis(phospholyl)acetylene that has been characterized by X-ray crystal structure analysis of its bis(pentacarbonylmolybdenum) complex. The reaction with sulfur leads to the corresponding disulfide that spontaneously undergoes a self-condensation via a Diels--Alder cycloaddition between the CC triple
