From P4to organic diphosphanes in a single operation: Photolysis of solutions containing P4 and readily available 1,3-dienes produces bicyclic organic diphosphanes, in a one-step, metal-free protocol. Use of 2,3-dimethylbutadiene or 1,3-butadiene (see drawing) allowed the isolation and solid-state structural characterization of the diphosphane products P2(C6H10)2 and P2(C4H6)2.
