The convenient preparation of some methyl, ethyl, vinyl and phenyl halo-arsines and -stibines by the action of the corresponding hydrocarbon halides on elementary arsenic and bismuth is described. Suitable conditions vary with the halide employed: methyl bromide and chloride react satisfactorily at 350–375° in the presence of copper as catalyst, but vinyl bromide and chloride require a temperature
描述了通过相应的烃卤化物对
单质砷和
铋的作用方便地制备一些甲基,乙基,
乙烯基和苯基卤代s啶和-stibines的方法。合适的条件随所用的卤化物而变化:在
铜作为催化剂的情况下,甲基
溴和
氯化物在350–375°时可令人满意地反应,但是
溴乙烯和
氯化物的温度至少要高出100°。
碘甲烷在280°下反应,但是收率很低。
银是
溴苯与
砷反应的上乘催化剂。
铋没有与
氯甲烷分离的产物,但是
溴甲烷使甲基二
溴铋的产率低。
