Claims16
Method for the preparation of alkali metal alcoholates by reacting alcohol with alkali metal in an aprotic organic solvent, characterised in that the synthesis is carried out in the presence of an H-acceptor, with the H-acceptor being an open-chain, unsubstituted or substituted 1,3-diene
- with R1, R2=H, alkyl, vinyl (R1, R2 in cis or trans position)
- or a cyclic 1,3-diene
- with n=1 to 5
- or an unsubstituted or substituted arylolefine
- with R3, R4=H, alkyl (R3, R4 in cis or trans position).
