cis-1,2-Bis(diphenylphosphino)ethene Nickel(0) Complexes

We have studied the ligand properties of cis-Ph2PCH=CHPPh2 at nickel(0).Several homoleptic nickel(0) alkene complexes react with the twofold molecular quantity of cis-Ph2PCH=CHPPh2 to afford the red crystalline homoleptic 1:2 complex Ni(cis-Ph2PCH=CHPPh2)2 (1).The reactions of Ni(cdt) or Ni(C2H4)3 with equimolar amounts of cis-Ph2PCH=CHPPh2 yield orange-yellow crystals of the homoleptic 1:1 complex n (2).Sparingly soluble 2 is presumably oligomeric with the (PCH=CHP)Ni moiety ?-bonded to another nickel(0) center.The ? bridges are rather stable and are only cleaved by strong ? acceptors.For example, 2 reacts with CO to yield the known carbonyl complex (cis-Ph2PCH=CHPPh2)Ni(CO)2 (3).In contrast to the above synthesis of 2, the 1:1 reaction of Ni(cod)2 with cis-Ph2PCH=CHPPh2 affords orange-red crystals of the alkene complex (cis-Ph2PCH=CHPPh2)Ni(cod)*THF (4) in moderate yield.Ni(1,5-hexadiene)2 reacts readily with cis-Ph2PCH=CHPPh2 (1:1) to give yellow (cis-Ph2PCH=CHPPh2)Ni(rac-η2,η2-C6H10) (5, 77percent), which exhibits a fluxional diene coordination.That these thermally labile alkene complexes are formed at all, is ascribed to the chelate effect of the dienes.From the reaction of 2, 4 or 5 with ethyne, yellow microcrystals of (cis-Ph2PCH=CHPPh2)Ni(C2H2)*Et2O (6) are obtained.
