On the Lewis Acidity of Nickel(0), II: Methylenetriorganylphosphorane Complexes of Nickel(0)

Methylenetriorganylphosphoranes R3P=CH2 (R = CH3, C6H5) react with Ni(CDT) and Ni(C2H4)3 to form the (methylenetriorganylphosphorane)(alkene)nickel(0) complexes (R3PCH2)Ni(CDT) (R = CH3, 2) and (R3PCH2)Ni(C2H4)2 (R = CH3, C6H5, 4, 5).On treatment with CO the ethene complexes give the known carbonyl complexes (R3PCH2)Ni(CO)3 (R = CH3, C6H5, 9, 10) in pure form. 2 and 4 decompose at room temperature to give Me3PNi(CDT) and Me3PNi(C2H4)2; cyclopropane is produced in the presence of ethene. - The stability of the CH2-Ni0 bond in the methylenetriorganylphosphorane complexes falls in the series Ni(CO)3 > Ni(C2H4)2 > Ni(CDT), corresponding to declining Lewis acidity of the nickel atom. 13C NMR evidence indicates that in the same sequence the P-CH2 bond also becomes weakened.The thermally induced elimination of methylene shows that the nickel bonded methylene group has appreciable carbenoid character.
