Structurally different bis(imino)copper(i) complexes were prepared in a highly modular manner and utilized as copper-based photocatalysts in the ATRA reactions of styrenes and alkyl halides. The new photocatalysts showed good catalytic activity and ensured efficient chemical transformations.

A simple, highly efficient and environmentally friendly microwave accelerated one-potsynthesis of a series of differently substituted bis-azetidinones have been synthesized expeditiously in good yields from 1,2-diaminoethane and aromatic aldehydes in the presence of zeolite. The structures of the newly synthesized compounds were confirmed by IR, NMR, and mass spectra. The design and calculated molecular

A nano tetraimine Pd(0) complex catalyst was successfully used as an efficient heterogeneous catalyst for the phosphine‐free palladium‐catalysed Suzuki coupling reaction in water at 80 °C. This nano tetraimine Pd(0) complex was also used for copper‐free Sonogashira reaction in dimethylformamide at 100 °C. The catalyst was easily recovered from the reaction mixture by centrifugation and reused for at
Synthesis of a nano tetraimine Pd(0) catalyst system using an N,N-bisimine ligand and its catalytic applications in the Heck–Mizoroki reaction in water is described.

Various solid carbamates were prepared from the reactions of liquid amines with carbon dioxide in an autoclave and these carbamates were used as stable, efficient alternatives for toxic liquid amines. Solid-state grinding of carbamates and aldehydes, using a mortar and pestle, produced imines as the sole products in greater than 97% yields. Complete conversions were generally accomplished within a
