Beta-nitrosubstituted trimethylsilylated alcohols RCH2-O-SiMe3 [R = N(
NO2)Me, C(NO2)Me2, C(NO2)2Me, C(NO2)3] have been studied. It has been
shown that the trimethylsiloxy group is sufficiently reactive only in
the N-nitro derivative in which it can be replaced by a chlorine atom
or dimethylamino group upon the action of trimethylchlorosilane or pen
tamethyldisilazane, respectively.
