A study of the decomposition reactions of benzenediazonium-2-car☐ylate, carried out in a number of mixed nucleophilic solvents, shows that a number of mechanistic pathways can operate simultaneously and can afford, in addition to products derived from benzyne, products derived from the 2-car☐yphenyl cation and the 2-car☐yphenyl radical: benzyne formation is favoured in halogenated solvents and occurs
在多种混合亲核溶剂中进行的苯二氮杂-2-car☐磺酸盐分解反应的研究表明,许多机理途径可以同时运行,并且除了苯并衍生产品外,还可以提供2-car☐yphenyl阳离子和2-car☐yphenyl自由基:在卤代溶剂中,苯并炔的形成是有利的,并且由于氮和二氧化碳的协同损失而发生。
