摘要
Halogen incorporated arenes and heteroarenes are often used as useful intermediates as well as target products in organic synthesis. Often, C-H bond halogenation is attempted using transition metals (Pd, Cu, Au, Rh etc.). However, keeping the environmental concerns in mind, transition metal free protocols are more relevant and essential in recent times. In this context, improvised methods are widely being developed to evade transition metals. A great deal of work has been done on this topic in recent times and still going on. The intention of this review is to cover recent works on transition metal-free C(sp(2))-H bond halogenations on arenes as well as heteroarenes.
