PhNH-N(PPh2)2 (1) with cobalt(II) silylamide, Co[N(SiMe3)2]2, proceeds via formation of unstable phosphinohydrazide complex Co[NPh-N(PPh2)2]2 followed by rearrangement to a new chelating compound Co(NPh-PPh2N-PPh2)2 (2). Disproportionation of nickel(I) silylamide, (Ph3P)2Ni-N(SiMe3)2, in the presence of 1, yields Ni(0) and Ni(II) phosphinoamide complexes: Ni[(Ph2P)2N-NPhH]2 (3), Ni(NPh-PPh2N-PPh2)2 (4). X-ray
