Reactions ofN-nitramines and their trimethylsilyl derivatives withN,N-bis(trimethylsilyloxy)enamines

Trimethylsilyl derivatives of methyl- and ethylnitramine react asN-centered nucleophiles with 2-N,N-bis(trimethylsilyloxy)aminopropene to give trimethylsilyl derivatives of hitherto unknown α-(N-nitro)alkylamino-substituted acetone oximes. As an ambident nucleophile, nonsubstituted methylnitramine reacts with the same enamine to give both a product of N,C-corss-coupling and a product of O,C-cross-coupling,viz., N′-methyl-N-[(2-trimethylsilyloxyimino)propoxy]diazeneN-oxide.
