A photoinduced iron-catalyzed ipso-nitration of aryl halides with KNO2 has been developed, in which aryl iodides, bromides, and some of aryl chlorides are feasible. The mechanism investigations show that the in situ formed iron complex by FeSO4, KNO2, and 1,10-phenanthroline acts as the light-harvesting photocatalyst with a longer lifetime of the excited state, and the reaction undergoes a photoinduced single-electron transfer (SET) process. This work represents an example for the photoinduced iron-catalyzed Ullmann-type couplings.

The amidation of aryl halides with alkyl/aryl isocyanides to give the corresponding amides using polymer-supported palladium-N-heterocyclic carbene complex (PS-Pd-NHC) as an efficient heterogeneous recyclable catalyst is described. The catalytic system was optimized with respect to various reaction parameters giving excellent yields of the desired products. The catalyst can be easily separated by a simple filtration process and recycled further for up to four consecutive recycle without any loss of activity and selectivity. The protocol is advantageous due to the ease in handling of the catalyst, simple workup procedure, phosphine-free, and effective catalyst recyclability. Georg Thieme Verlag Stuttgart New York.
