As convenient intermediates to introduce methyl groups into the o-positions of phenols, o- methylthiomethylphenols (o-MTM-phenols) were prepared in high selectivity and moderate yield by the reaction of phenols with sulfilimines such as S, S-dimethyl-N-(2, 4-dinitrophenyl)- and S, S-dimethyl-N-tosylsulfilimines.
