A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 7650-91-1, Name is Benzyldiphenylphosphine, molecular formula is C19H17P.

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.
