Исследовано О-алкилирование пирокатехинов и салицилового спирта 4-хлорметил-1,3-диоксоланом. Селективность образования эфиров в значительной степени определяется строением исходных реагентов и условиями проведения процесса (растворитель, температура, соотношение реагентов). Показано, что микроволновое излучение позволяет сократить продолжительность реакции и повысить выход монои диэфиров.
There are investigated the O-alkylation of catechol and salicylic alcohol 4-chloromethyl-1,3-dioxolanes. Selectivity of formation of ethers is largely determined by the structure of initial reagents and process conditions (solvent, temperature, ratio of reagents). It is shown that microwave radiation can reduce the duration of the reaction and increase the yield of monoand di-ethers.
