在甲苯中可以从三氯化硼及对溴苯胺一步合成(C1B·N·C6H4·Br-P)3,产品含半分子甲苯(Ⅰ).若改用氯苯作溶剂,則得不含溶剂的产品(Ⅱ).本文并研究合成条件对产率的影响,找出加入三乙胺不能提高产率.B-苯基衍生物的粗产物易自氧化而遭破坏,但相应的脂肪烴基衍生物則較稳定.仲丁基衍生物的得率可采用在乙醚中长期回流的方法而提高.在本实驗中合成六种(RB·N·C6H4·Br-P)3(R=C6H5,CH3,n-C4H9,i-C4H9,sec-C4H9,CH2=CHCH2)型化合物.(CH3B·N·C6H4·Br-p)3的产率为56%.据初步实驗的結果表明B-三烯丙基-N-三对溴苯基硼氮六环不易自行聚合.

In toluene,the π-molecular orbital complex(ClB·N·C6H4·Br-P)3·1/26H5CH3 was prepared from boron trichloride and p-bromoaniline by one-step reaction.In chlorobenzene,only(ClB·N·C6H4·Br-P)3 was obtained.A tentative explanation was suggested.
