Selective cis-isomerization of 1-pentene was carried out by NiX(PPh3)3 (X = halogen and pseudohalogen).First-order plots were obtained except for the iodo-complex.The addition of tin(II) chloride increased both activities and ratios of cis-2-pentene to the trans-isomer.Protic solvents accelerated the isomerization.Isotopic exchange between C2D4 and C2H4 or 1-pentene reveals that a metal hydride addition-elimination mechanism is operative.

The reagent [(o-C6H4PPh2NSiMe3)Li]2 ·Et2O 1 reacted with BCl3 affording (o-C6H4PPh2NSiMe3)BCl2 4. Similarly reaction of 1 with Me2AlCl resulted in a 1:1 mixture of (o-C6H4PPh2NSiMe3)AlMe2 5 and (o-C6H4PPh2NSiMe3)-Al(Me)Cl 6 while the analogous reaction of 1 with GaCl3 gave (o-C6H4PPh2NSiMe3)2 Ga(o-C6H4PPh2NH) 7. The analogous compound [Li(o-C6H4PPh2NPh)]2· Et2O 2 was used to make (o-C6H4PPh2NPh)GaCl2 8, while reaction of 2 with Me2AlCl gave a mixture of [(o-C6H4PPh2NPh)AlCl2] 9 and the salt [(o-C6H4PPh2NPh)2Al] [AlMeCl3] 10. The compound 2 also reacts with PdCl2(COD) affording [Pd(o-C6H4PPh2NPh) (μ-Cl)]2 11 and [Pd(o-C6H4PPh2 NPh)2] 12. Similarly, the complexes [Ni(o-C6H4 PPh2NPh)2] 13 and [Ni(o-C6H4PPh2N(3,5-C6H3 Me2))2] 14 were prepared. The compounds 4-14 have been structurally characterized by X-ray methods.

The interaction of (η2-ethylene)bis(triphenylphosphine)nickel(0) with 1-bromo-2-methyl-2-phenyl- and 1,1,-dibromo-2-methyl-2-phenyl-cyclopropane has been studied.These reactions were expected to proceed with opening of the three-membered ring a
