inert medium, such as 1,1,2-trichlorotrifluoroethane (CF2CICFCl2) or perfluorocarbon, and elemental fluorine is passed through the system at room temperature. High conversions to iodoaromatic products occur, even with some deactivated systems, e.g. nitrobenzene. A very powerful brominating system is produced using the analagous methodology.
已经开发出用于直接碘化苯类化合物的新方法。将芳族底物简单地与碘和硫酸混合,悬浮在惰性介质中,例如1,1,2-三氯三氟乙烷(CF 2 CICFCl 2)或全氟化碳,并使元素氟在室温下通过该系统。即使使用某些失活的系统(例如硝基苯),也可能发生向碘代芳烃产品的高转化。使用类似的方法可以生产出功能强大的溴化系统。
