Amz. Slawin et Mb. Smith, SYNTHESIS AND CHARACTERIZATION OF NEW METALLACYCLES CONTAINING [PH2P(E)NP(E)PH-2](-) (E = S OR SE) LIGANDS, Phosphorus, sulfur and silicon and the related elements, 125, 1997, pp. 481-484
Reaction of [Ph2P(E)NP(E)Ph-2](-) (E = S or Se) with a series of late
transition-metal dimers, in thf or MeOH, leads to facile bridge cleava
ge and formation of new mononuclear compounds.
