Zusammenfassung:The invention relates to new compounds of the general formulae (I) and/or (II), (I) (II) wherein R1 is a C1-6 alkyl or an aralkyl group, and R2 is hydrogen or a C1-6 alkyl group. According to another aspect of the invention there are provided processes for the preparation of these compounds. The compounds of the general formulae (I) and/or (II) are utilizable for the oxymation and/or trimethylsilylation of any substrate bearing an oxo group and/or a silylable polar hydrogen. The compounds of the general formula (VI): (CH3)3Si-Y-Z=N-OR1 (VI) wherein R1 is as defined above Y is oxygen, nitrogen or sulphur atom or a carboxylate anion, and Z is the skeleton of the substrate, said compounds being formed in the oxymation and/or trimethylsilylation reaction, are also within the scope of the invention.
