Application
4-溴甲苯可用于通过Cu/Pd催化的脱羧交叉偶联反应而合成酮。
General description
4-溴甲苯是 对位取代的芳基溴。在CuI/K2CO3/phen体系的催化下，4-溴甲苯可与2,4-二甲基苯酚发生C-O偶联反应。据报道，配合物[Cu（phen）（1-（2,4-二甲基苯氧基）-4-甲基苯]]+、 {H[Cu(phen)(2,4-dimethylphenoxy)]}+ 和[Cu(2,4-dimethylphenoxy)2]-可作为原位电喷雾电离质谱（ESI-MS）分析反应的中间体。已有研究报道了使用乙酸钯（II）催化的4-溴甲苯与非荧光苯基硼酸（PBA）的Suzuki偶联反应。已有研究描述了在微结构连续反应器中钯催化的4-溴甲苯与哌啶的C-N交叉偶联反应。据报道，当存在原位生成的膦官能化N-杂环卡宾配体的钯配合物时，4-溴甲苯与苯乙烯会发生Heck反应。

The fluorogenic derivatization method for aryl halide was developed for the first time. This method was based on the formation of fluorescent biphenyl structure by Suzuki coupling reaction between aryl halides and non-fluorescent phenylboronic acid (PBA). We measured the fluorescence

The C-O coupling reaction between 2,4-dimethylphenol and 4-bromotoluene catalyzed by the CuI/K2CO3/phen system can be inhibited by the radical scavenger cumene. Complexes [Cu(i)(phen)(1-(2,4-dimethylphenoxy)-4-methylbenzene)](+) (denoted as A), {H[Cu(i)(phen)(2,4-dimethylphenoxy)]}(+) and [Cu(i)(2,4-dimethylphenoxy)2](-) (denoted as B) were observed by in situ electrospray ionization mass
