| Research Abstract |
When treated with Me_3 SiI of CF_3SO_3SiMe_3 in benzene, a series of dinitrogen complexes (M(N_2)_22(L)_4) (M = W, Mo: L = tertiary phosphine) afforded trimethlsilyldiazenido (MNNSiME_3) andteimethylsilyihydrazido(2-) (MNNHSiMe_3) complexes under mild conditions. The former compiexes well correspond to the intermediate stage from molecular nitrogen toward silyldiazanes, although we have not yet succeeded in the conversion of the silyldiasinido groups into silyldiazenes. On the other hand, we have recently found that treatment of Me_3SiCl with Na dispersion if THF at 30゜c under atmospheric pressure of N_2 gives N(SiMen13n2)_3 and HN(SiMe_3)_2 in the presence of cis-(Mo(N_2)_2(PMe_2Ph)_4). The formation of silylamines is catalytic and the maximum yield observed till now is 38% based on Me_<23>SiCl chatged, which correspones to the turnover number of 25 based on the molybdenum. The catalytic activity of the tungsten analogue was much lower than that of the molybdenum complex under the same reaction conditions.
