Abstract:
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 ##STR2##with R.sub.1, R.sub.2 =H, alkyl, vinyl (R.sub.1, R.sub.2 in cis or trans position)or a cyclic 1,3-diene ##STR3##with n=1 to 5or an unsubstituted or substituted arylolefine ##STR4##with R.sub.3, R.sub.4 =H, alkyl (R.sub.3, R.sub.4 in cis or trans position).
