This electron-rich derivative of benzophenone is an intermediate in the production of dyes and pigments, for example Methyl violet. It is also used as a photosensitizer. It is named after the German chemist Wilhelm Michler. ==Synthesis== The ketone is prepared today as it was originally by Michler using the Friedel-Crafts acylation of dimethylaniline (C6H5NMe2) using phosgene (COCl2) or equivalent reagents such as triphosgene (Me = methyl): :COCl2 + 2 C6H5NMe2 → (Me2NC6H4)2CO + 2 HCl The related tetraethyl compound (Et2NC6H4)2CO, also a precursor to dyes, is prepared similarly. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Michler's ketone」の詳細全文を読む スポンサード リンク
