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 Q=C triple bond and the phosphole dienic system giving, after aromatization by loss of the phosphorus bridge, the corresponding 1,2-bis(phospholyl)benzene.
