The factors favouring formation of biphosphine disulphides are identified and evidence is presented (a) for attack by the Grignardreagent on chlorine, and (b) that phosphorus–phosphorus bond formation does not occur when two organic groups are attached to phosphorus. A mechanism is proposed, involving simultaneous removal of two halogen atoms from the thiophosphorus halide yielding a phosphinidene
