Abstract

Abstract Alkylation of pyrocatechol with tert-butyl alcohol in benzene in the presence of sulfuric acid gave 3, 5-di-tert-butylbenzene-1, 2-diol in a higher yield than in analogous reaction with tert-butyl alcohol. This result was rationalized by reduction of inhibitory effect of liberated water, formation of heterogeneous system, and occurrence of the alkylation process in nonpolar organic phase. Intermediate products were identified and found to ...
