New and valuable pyrocatechol derivatives and a process for their preparation. The pyrocatechol derivatives have the formula ##STR1## wherein: R denotes alkyl of from 1 to 4 carbon atoms which may be substituted with halogen; alkenyl having up to 4 carbon atoms which may be substituted with halogen; alkynyl having up to 5 carbon atoms which may be substituted with halogen; or benzyl; R.sup.1 denotes hydrogen or alkyl of from 1 to 4 carbon atoms; R.sup.2 denotes benzyl or alkyl of from 1 to 3 carbon atoms which may be substituted with halogen, methoxy or ethoxy; R.sup.3 denotes alkyl of from 1 to 4 carbon atoms; cycloalkyl of from 3 to 7 carbon atoms; .beta.-chlorethyl; methoxyethyl; ethoxyethyl; alkenyl of from 2 to 4 carbon atoms; alkynyl of from 2 to 4 carbon atoms; acetyl; propionyl; R.sup.1 and R.sup.2 when taken together with the carbon atom to which they are attached form a cyclopentyl or cyclohexyl ring; and R.sup.1 and R.sup.3 when taken together with the carbon atom and oxygen atom to which they are attached form a tetrahydrofuranyl or tetrahydropyranyl ring. These compounds I are valuable starting materials for cleavage of the acetal structure to yield a pyrocatechol monoether of the formula ##STR2## in very high yields while retaining the R member, such monoethers preferably being reacted with methyl isocyanate to form N-methylcarbamates which have a pesticidal action.
