一般描述

溴化铜是一种单斜晶体材料。它易溶于水、乙醇和丙酮。它可通过使用氢溴酸中和铜的氧化物、碳酸盐或氢氧化物来进行合成。另一种合成技术是通过用溴水或溴的乙醇溶液来对铜进行氧化。[1]

应用

溴化铜在有机反应中可用作催化剂和溴化剂。[1]铜催化的乙炔封端的聚乙二醇甲基醚甲基丙烯酸酯（PEGMEMA）链的生物素化已被研究。[2]乙腈中的二溴化铜可在缩醛向双（甲氧基苯基）甲基（BMPM）醚的相互转化中充当催化剂。[3]它已作为一种催化剂用于α-羰基的分子内脱羧官能化以生成用于合成呋喃[3,2-c]香豆素的C(sp(3))-O键。[4]聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS）已被报道在掺杂CuBr2后可充当聚合物太阳能电池（PSC）中的空穴传输层（HTL）。这种掺杂增加了电导率，从而提高了PSC的器件功率转换效率。 [5]
