Reactions of lithium salts of triphosphines tBu2P–PLi–PtBu2 and tBu2P–PLi–P(NEt2)2 with metal complexes [(R3P)2MCl2] (M = Ni, Pd, Pt, R3P = Et3P, pTol3P, Ph2EtP, iPr3P)

tBu2P–PLi–PtBu2•2THF reacts with [(R3P)2MCl2] (M = Pt, Pd, Ni) yielding isomers of [(1,2-η-tBu2P=P–PtBu2)M(PR3)Cl] where tBu2P–P–PtBu2 ligand adopts the geometry of a side-on bonded 1,1-di-tert-butyl-2-(di-tert-butyl¬phosphino)¬di¬phosphenium cation. tBu2P–PLi–P(NEt2)2•2THF reacts with [(R3P)2MCl2] but does not formed complexes with a tBu2P–P–P(NEt2)2 moiety, however, splitting of a P–P(NEt2)2 bond of the parent triphosphine takes place.
