(PhMe2As)4Ni and CF3CCCF3, and the triphenylphosphine complex is formed by reaction of (Ph3P)2Ni(C2H4) with hexakis(trifluoromethyl)benzene. Treatment of the binuclear complex with (MeO)3P or MeC(C H2O)3P gives [(MeO)3P]4Ni2[C6(CF3)6] and [MeC(CH2O)3P]4Ni2[C6(CF3)6], respectively. It is suggested that these complexes are fluxional hexakis(trifluoromethyl)benzenenickel (II) compounds.
六氟丁-2-炔与双(环辛-1,5-二烯)镍反应形成(1,5-C 8 H 12)Ni [C 6(CF 3)6 ]和(1,5-C 8 H 12)2 Ni 2 [C 6(CF 3)6 ](1,5-C 8 H 12 =环辛-1,5-二烯)。环辛基-1,5-二烯被Ph 2 PMe,PhMe 2 As,Ph 3 P,(MeO)3 P,MeC(CH 2 O)3 P从单核络合物取代,得到络合物L 2 Ni [ C6(CF 3) 6 ] [L = Ph 2 PMe,PhMe 2 As,Ph 3 P,(MeO) 3 P和MeC(CH 2 O) 3 P]。(络合物也由(PhMe 2 As) 4 Ni和CF 3 CCCF 3形成,并且三苯基膦络合物由(Ph 3 P) 2 Ni(C 2 H 4)与六(三氟甲基)苯反应形成。用(MeO) 3 P或MeC(CH 2 O) 3 P处理双核复合物可得到[(MeO)3 P] 4
