Preparation or ortho-methyl anilines from ortho-amino benzyl sulfoxides. |
摘要 |
<p>This invention relates, in one of its aspects, to a process for the preparation of ortho-methyl anilines from ortho-amino benzyl sulfoxides. An ortho-amino benzyl sulfoxide is converted to an ortho-amino benzyl halide by reaction with a nonoxidizing acid halide and is converted to a stable quaternary salt by reaction with a tertiary amine preferably in the presence of an alcohol. The quaternary salt may be cleaved by hydrogenation to form ortho-methyl anilines. Other aspects of the invention relate to novel intermediate quaternary salts and to a process for forming those quaternary salts.</p> |
