AlCl_3催化合成苯基二氯化膦及其反应机理的探讨

Synthesis of dichlorophenylphosphine by aluminium chloride and its reaction mechanism

以苯和PCl3为原料,在三氯化铝催化作用下,通过Friedel-Crafts反应合成了苯基二氯化膦,对该反应机理进行了探讨。研究发现,160目的NaCl能有效地分离出催化剂三氯化铝,苯基二氯化膦的收率达86.5%。对NaCl与三氯化铝形成配合物的原因进行了探讨。

Dichlorophenylphosphine was synthesized from benzene and phosphorous trichloride using aluminum chloride as the catalyst, and its reaction mechanism studied. It was found that sodium chloride with particle size of 160 mesh effectively separated aluminum chloride, with dichlorophenylphosphine yield of 86.5%. The cause behind formation of complex of sodium chloride and aluminum chloride was discussed.
