一步法合成1,1-二苯乙烷

One-step synthesis of 1,1-diphenylethane

以苯、乙醛为原料,三氯化铝为催化剂,在20℃,苯、乙醛、三氯化铝物质的量比为10.0∶1.0∶1.1～1.2,反应时间为5h,得到1,1-二苯乙烷,收率54.0%。通过氢核磁谱和红外吸收光谱对该合成产物进行了结构验证。

1, 1-Diphenylethane was synthesized from benzene, ethyl aldehyde and aluminium trichloride as raw materials with molar ratio of 10.0：1.0：1.1- 1.2 at20℃ for5 h.The yield of 1,1-diphenylethane was beyond 55.0% . The structure of 1,1- diphenylethane was confirmed by I HNMR and infrared spectra.
