摘要

Contrary to p-quinone methides, the addition of primary alcohols to p-benzo-fuchsone (II) requires the presence of a catalytic amount of hydrogen chloride or p-toluenesulfonic acid. As the reaction product, the 4-hydroxybenzyl ether V is obtained in an almost quantitative yield. If the reaction is conducted at the boiling point of the alcohol, the composition of reaction. mixture depends on the reaction time. When the reaction was stopped ...
