A series of novel (77 -l-azaallyl)-Ni complexes 91 and 92 has been reported recently.The solid-state structures of these complexes confirm the 77 -coordination of the azaallyl ligands (Ni-C 203-206 pm Ni-N 188-192 pm). Variable-temperature NMR studies have shown that 91 and 92 undergo a dynamic process in solution that generates three different isomers, presumably via 77 /7/ -slippage processes. [Pg.158]

Reaction of but-2-yne with [(RNH)(RN=)2V(OEt2)] (R = Bu 3Si) resulted 33 in displacement of the diethyl ether ligand and formation of [(RNH)(RN=)V C(Me>=C(Me)N(R))l which underwent ligand metallation to afford the ri -i-azaallyl complex (15). The synthesis and reactions of the 16-electron bis-(Ti3-allyl) tantalum species [Cp Ta( n3.phCHCHCH2)2] have been reported 34 and the X-ray crystal structure determined 35. [Pg.337]
