16-Electron complexes of zerovalent nickel with diallylamines, Ni[(C3H5)2NR]L [1, 2: L = P(CH3)3, R = CH3, C6H5; 3: L = P(C6H5)3, R = CH3] and [NiP(CH3)3]2CH2[N(C3H5)2]2 (4), were synthesized by reduction of NiCl2L2 with magnesium in tetrahydrofuran. NiCl(η3-C3H5)[P(CH3)3]2 (5), a low-yield byproduct, was also obtained in high yield from NiL4 and C3H5Cl. With triallylamine as starting material complexes Ni[(C3H5)3N]L [6: L = P(CH3)3; 7: L = P(C6H5)3] were generated exhibiting η6- and η4-olefin coordination, respectively. 17-electron cobalt(O) compounds Co[(C3H5)2NR](PMe3)2 (8, 9: R = CH3, C6H5) were obtained by reaction of Co(cyclo-C5H8)(PMe3)3 with the corresponding diallylamine, while CoR(PMe3)4 (R = CH3, C6H5) reacted with N,N-diallylaniline to give diagmagnetic Co[(η3-C3H4)(η2-C3H5)NC6H5](PMe3)2, (10). The coordination mode of allylic functions was deduced from IR, ESR and especially 1H- and 13C-NMR spectra including 2D-NMR experiments.
