Abstract
The present invention relates to new hexacoordinate silicon complexes, the process for their preparation and their application. These new complexes correspond to the general formula I: ##STR1## in which: A represents an alkali metal or alkaline earth metal except for magnesium, and n=0 or 1.
Claims20
A hexacoordinate silicon complex which corresponds to the general formula I:
- ##STR22## in which:
- A represents an alkali metal or alkaline earth metal except for magnesium, and
- n=0 or 1.
An application of the complexes of the general formula I:
- ##STR23## in which:
- A represents an alkali metal or alkaline earth metal and
- n=0 or 1, to the preparation of organosilanes of the formula II:
- R.sub.3 Si--R' (II)
- in which:
- R denotes n alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, aralkynyl or alkylaryl radical in which the aliphatic fragments are linear, branched or cyclic and contain from 1 to 20 carbon atoms, or alternatively a radical SiR".sub.3, in which R" denotes a radical R, and
- R' denotes a hydrogen or halogen atom or alternatively a radical R, which comprises reacting an organometallic derivative with the abovementioned hexacoordinate silicon complex of the general formula I.
