Two radical‐mediated processes of activatedalkenes, namely arylphosphonylation and arylazidation, are described. The difunctionalization of alkenes by a tandem process that involves radical addition, 1,4‐aryl migration, and desulfonylation generates α‐aryl‐β‐heterofunctionalized amides bearing a quaternarystereocenter when the substituent on the nitrogen atom is an aryl group. Alternatively, heterooxindoles
A new, general method for the synthesis of phosphonoisoquinolinediones has been achieved via copper-catalyzed phosphonation–cyclization of various methacryloylbenzamides with P(O)H compounds. This transformation allows the direct formation of a P–C bond and the construction of an isoquinolinedione ring in one reaction.
