Abstract

A process for the preparation of substituted 4,6-dilithophenols of the formula: ** (See formula) ** where R1 represents an alkyl radical containing at least two carbon atoms or a cycloalkyl, aralkyl or aryl radical, optionally substituted, and R2 represents a hydrogen atom or an alkyl radical; said method being characterized in that it comprises subjecting a substituted phenol of the formula: ** (See formula) ** where R1 and R2 are as defined above, at a direct nitration with diluted nitric acid only, at a concentration lower than 70% by weight and at a temperature above 10º C but less than or equal to the boiling temperature of the reaction medium, using an excess of nitric acid such that the final concentration of residual acids after nitration is at least 4%.
