The interaction of (Ph2PN)C(Ph)[N(SiMe3)2] (L1) with one equivalent of Mn(CO)5Br afforded cis-Mn(CO)4Br(Ph2PN)C(Ph)[N(SiMe3)2]} (1), which upon boiling in THF gave fac-Mn(CO)3Br[(Ph2PNH)C(Ph)(NSiMe3)] (2), and with one equivalent of Re(CO)5X (X=Br or Cl) gave fac-Re(CO)3X[(Ph2PNH)C(Ph)(NH)] [X=Br (3) or Cl (4)] in good yield. Reaction of 1,4-C6H4C(NPPh2)[N(SiMe3)2]}2 (L2) with two equivalents
