temperature and useful application of synthesized molecules. The rarely explored chemistry of NiFe2O4 towards the X–N cross-coupling reaction well complements conventional methods for the synthesis of S–N or Se–N heterocycles. Nickel ferrite nanoparticles were prepared by a simple hydrothermal method and characterized by using XRD, SEM, TEM, HRTEM, SAED, energy dispersive X-ray spectroscopy, XPS, ICP-AES and
atom-economic method for the regiodivergent synthesis of crucial 6- or 8-substituted indolizine from meta-amide-substituted pyridine and alkyne via a [2 + 2 + 1] cycloaddition is developed. The reaction proceeds through the cleavage of the carbon–carbon triple bond. The synthesized product contains an important amide group that can be further functionalized to afford biologically active compounds.

A novel Pd-catalyzed assembly of N-phenylphthalimide by merging of [4+1] cycloaddition and difluorocarbene transfer carbonylation from 2-iodo-N-phenylbenzamides and difluorocarbene precursors is disclosed. In this reaction, difluorocarbene acts as a carbonyl source and simultaneously forms one C-C bond, one C-N bond and one C=O bond to produce N-phenylphthalimides in high yields.
