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.
作为在苯酚邻位引入甲基的便捷中间体,邻甲硫甲基苯酚(o-MTM-苯酚)通过苯酚与硫亚胺(例如S,S-二甲基-N-)反应以高选择性和中等收率制备。 (2,4-二硝基苯基)-和S,S-二甲基-N-甲苯磺酰硫亚胺。
