| 摘要 |
Ortho-hydroxybenzyl alcohols are obtained from phenols having an unsubstituted ortho-position by reacting the phenol with a boric acid or boron trioxide, treating the reaction product with formaldehyde and hydrolysing the resulting ortho-hydroxybenzyl metaborate ester in the presence of an ester R1-O-R2, where R1 and R2 are alkyl, alkoxyalkyl or aryl, preferably diisopropyl ether. |
