Cobalt-catalyzed regioselective diazidation of 1‑aryl-1,3-dienes enabled by a single electron transfer/radical addition/group transfer relay process

A novel cobalt-catalyzed 1,2-diazidation of 1‑aryl-1,3-dienes by using TMSN3 as azide source has been reported. A series of vicinal diazides containing unsaturated bonds that are amenable to further functionalization were...
