N, N-Dimethyl-(1- or 2-naphthylmethyl)ammonium N-methylide (2a, b) produced from N, N-dimethyl-N-[(trimethylsilyl)methyl](1- or 2-nephthylmethyl)ammonium iodide (1a, b) with CsF in N, N-dimethylformamide, was rearranged to 2[(dimethylamino)methyl]-1, 2-dihydro-1-naphtholidene (3a) or 1-[(dimethylamin)methyl]-1, 2-dihydro-2-naphtholidene (3b), respectively, in high yield. Aromatization of 3a, b to the Sommelet-Hauser products(4a, b) occurred with the aid of KOH or heating.
由 N,N-二甲基-N-[(三甲基硅基)甲基](1-或 2-萘甲基)碘化铵(1a,b) 与 CsF 在 N、N-二甲基甲酰胺中用 CsF 对碘化铵(1a、b)进行重排,分别高产出 2[(二甲基氨基)甲基]-1,2-二氢-1-萘烷(3a)或 1-[(二甲基氨基)甲基]-1,2-二氢-2-萘烷(3b)。在 KOH 或加热的帮助下,3a、b 芳香化为索姆雷特-豪泽尔(Sommelet-Hauser)产物(4a、b)。
