Reactivity of [M(CO)4(nbd)] (M = Cr or Mo; nbd = norbornadiene) toward (Ph2PN)C(Ph)[N(SiMe3)2] and C6H4{C[N(SiMe3)2]-(NPPh 2)}2-1,4

The interaction of (Ph2PN)C(Ph)[N(SiMe3)2] with 1 equivalent of [M(CO)4(nbd)] (M = Cr or Mo, nbd = norbornadiene) in diethyl ether gave cis-[M(CO)4{(Me3SiN)C(Ph)(NHPPh2}] (M = Cr 1 or Mo 2) in good yield. The interaction of C6H4{C(NPPh2)[N(SiMe3) 2]}2-1,4 with 2 equivalents of [M(CO)4(nbd)] (M = Cr or Mo) in tetrahydrofuran gave the symmetric dimer cis-[{M(CO)4} {(Ph2PNH)(Me3SiN)CC6H4C(NSiMe 3)(NHPPh2)}] (M = Cr 3 or Mo 4) in moderate yield. However, in diethyl ether, this reaction (M = Mo) gave the unsymmetric cis-[(OC)4Mo{(Ph2PNH)(Me3SiN)CC 6H4C[N(SiMe3)2](NPPh 2)}Mo(CO)5] 5 in moderate yield. Compounds 1-5 have been fully characterized by analytical and spectroscopic methods and the structures of 3 and 5 have been established by X-ray crystallography. A 1,3-silyl shift mechanism has been proposed for the formation of the products. The NH proton of the bidentate iminophosphine ligand undergoes facile deuterium exchange with D2O at ambient temperature.

The interaction of (Ph2PN)C(Ph)[N(SiMe3)2] with one equivalent of C7H8Cr(CO)4 in diethyl ether gave cis-(CO)4Cr[(Me3SiN)C(Ph)(NHPPh2)] in good yield. The compound has been fully characterized by analytical, spectroscopic and X-ray diffraction methods. The NH proton of the bidentate iminophosphine ligand undergoes facile deuterium exchange with D2O at ambienttemperature. A 1,3-silyl shift mechanism has been proposed for the form ation of the product.
