This invention relates to a process for the hydroxylation of napthalene to .varies. and .beta. naphthols which comprises reacting napthalene with hydrogen peroxide in the presence of a solid catalyst containing an organotransition metal complex wherein some or all of the hydrogen atoms of the said organotransition metal complex have been substituted by one or more electron withdrawing group in the presence of solvents, with or without promoter and isolating the naphthols formed by conventional methods.

Process for the preparation of .alpha. and .beta. napthol by

An improved process is provided for the preparation of a mixture of guaiacol and p-methoxy phenol which comprises reacting anisole with hydrogen peroxide in the presence of a solid catalyst containing an organotransition metal complex wherein some or all of the hydrogen atoms of the said organotransition metal complex have been substituted by one or more electron withdrawing groups, and isolating the mixture of guaiacol and p-methoxy phenol formed.
