A novel oxidative procedure for the synthesis of benzamides from styrenes and amines under metal-free conditions.

An interesting procedure for the oxidative synthesis of amides from styrenes and amines has been developed. Various primary amides were formed in moderate yields (25-81%). Secondary amides can be produced in moderate yields as well (41-68%). Notably, no transition metal catalyst was needed for this transformation. This is the first example of oxidative transformation of styrenes to benzamides.
