1,2,3-Tris(arylmethylene)cyclohexanes (eleven examples) are prepared by aldol condensation from aromatic aldehydes and cyclohexanones, followed by Wittig olefination. They are rearranged nearly quantitatively by gasous hydrogen bromide to 1,2,3-tris(arylmethyl)benzenes.
1,2,3-三(芳基亚甲基)环己烷(十一种例子)通过芳香醛和环己酮的但偶缩合反应制备,然后通过Wittig烯化反应。它们通过气态溴化氢几乎定量重排为1,2,3-三(芳基甲基)苯。
