Abstract
The invention relates to new compounds of the general formulae (I) and/or (II), ##STR1## wherein R.sup.1 is a C.sub.1-6 alkyl or an aralkyl group, and PA0 R.sup.2 is hydrogen or a C.sub.1-6 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): EQU (CH.sub.3).sub.3 Si--Y--Z=N--OR.sup.1 (VI) wherein PA0 R.sup.1 is as defined above PA0 Y is oxygen, nitrogen or sulphur atom or a carboxylate anion, and PA0 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.
