Metallated triphenylphosphinimine complexes

The reagent [(o-C6H4PPh2NSiMe3)Li]2·Et2O 1 reacted with BCl3 affording (o-C6H4PPh2NSiMe3)BCl24. Similarly reaction of 1 with Me2AlCl resulted in a 1 : 1 mixture of (o-C6H4PPh2NSiMe3)AlMe25 and (o-C6H4PPh2NSiMe3)Al(Me)Cl 6 while the analogous reaction of 1 with GaCl3 gave (o-C6H4PPh2NSiMe3)2Ga(o-C6H4PPh2NH)7. The analogous compound [Li(o-C6H4PPh2NPh)]2·Et2O 2 was used to make (o-C6H4PPh2NPh)GaCl28, while reaction of 2 with Me2AlCl gave a mixture of [(o-C6H4PPh2NPh)AlCl29 and the salt [(oC6H4PPh2NPh)2Al][AlMeCl3]10. The compound 2 also reacts with PdCl2(COD) affording [Pd(o-C6H4PPh2NPh)((mu)-Cl)]211 and [Pd(o -C6H4PPh2NPh)2]12. Similarly, the complexes [Ni(o-C6H4PPh2NPh)2]13 and [Ni(o-C6H4PPh2N(3,5-C6H3Me2))2]14 were prepared. The compounds 4-14 have been structurally characterized by X-ray methods.
