A novel and direct metal-free nitro-carbocyclization of activated alkenes leading to valuable nitro-containing oxindoles via cascade C-N and C-C bond formation has been developed. The mechanistic study indicates that the initial NO and NO2 radical addition and the following C-H functionalization processes are involved in this transformation.

A sliver of silver: An efficient silver-promoted azido-carbocyclization of activated alkenes via a radical pathway has been developed. Azido oxindoles, which hold great potential for subsequent transformation of the azido unit, are efficiently constructed by this protocol. Radical addition and C - H functionalization processes are involved in this transformation with the formation of C - N and C - C bonds. Silver is observed to promote the single-electron oxidation process. Copyright
