ABSTRACT:
4-(.alpha.-hydrocarbyl-.alpha.-cyano-methyl)2,6-di-substituted phenols having the formula ##STR1## wherein R is selected from hydrogen, hydrocarbyl radicals, substituted hydrocarbyl radicals and hydrocarbyloxy radicals and R.sub.1 and R.sub.2 are the same or different monovalent substituent selected from the group consisting of alkyl, aralkyl and cyclic alkyl radicals and are prepared by reacting a di-substituted phenol having the formula ##STR2## when R.sub.1 and R.sub.2 are as defined above with an aldehyde having at least one aldehyde radical and containing an R group as defined above and an alkali metal cyanide or an alkaline earth metal cyanide in a suitable solvent. The 4-(.alpha.-hydrocarbyl-.alpha.-cyano-methyl)2,6-di-substituted phenol thus formed can readily be converted to the corresponding 4-(.alpha.-hydrocarbyl-.alpha.-cyano-methyl)-phenol by dealkylating the substituent groups ortho to the hydroxyl group from the 4-(.alpha.-hydrocarbyl-.alpha.-cyano-methyl)-2,6-di-substituted phenol which then can be converted on hydrolysis to the corresponding .alpha.-hydrocarbyl-4-hydroxyphenylacetic acid. These acids are insecticidal and acaricidal intermediates and are deemed to have utility as insecticides themselves as are the 4-(.alpha.-hydrocarbyl-.alpha.-cyano-methyl)2,6-di-substituted phenols of the present invention.
