Process for the preparation of resorcinol derivatives

Abstract

2-Substituted-4,6-di-t-butylresorcinol represented by the general formula: ##STR1## wherein R represents a straight or branched alkyl group having 1 to 20 carbon atoms, a straight or branched alkenyl group having 2 to 20 carbon atoms and at least one double bond, or an aralkyl group, but the tertiary carbon atom of R is free from direct bonding to the benzene nucleus, is prepared by allowing 4,6-di-t-butylresorcinol to react with a halogen compound represented by the general formula: RX wherein R has the same meaning as defined above, and X represents a halogen atom, excluding the X bonded to the tertiary carbon of R, in an aqueous alkali solution. By further debutylization of the 2-substituted-4,6-t-butylresorcinol, 2-substituted resorcinol represented by the general formula: ##STR2## wherein R has the same meaning as defined above, but the tertiary carbon of R is free from direct bonding to the benzene nucleus, is prepared.
