Massspectral fragmentation patterns of dimethylsilyl (DMS) ethers of primary unbranched, branched, and secondary unbranched aliphatic alcohols in the C5 to C10 range are compared with those of the corresponding trimethylsilyl (TMS) derivatives. Unlike their TMS analogues, DMS ethers of primary alcohols exhibit pronounced rupture of the CC bond adjacent to the oxygen atom within the alkyl moiety (loss

An uncatalyzed method for the silylation of alcohols and phenols with HMDS in CH3NO2 at rt is developed. A diverse range of aromatic and aliphatic alcohols as well as phenols undergo the silylation in very short reaction time with excellent yield. The uncatalyzed reaction requires neither elevated temperature nor high pressure for the silylation.

Primary and secondary benzylic and secondary alkyl trimethlysilyl ethers are efficiently converted into their carbonylcompounds by NaBrO3-NH4Cl in aqueous acetonitrile. Primary alkyl silyl ethers give only the corresponding alcohols without further oxidation with NaBrO3-NH4Cl.
