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.
-Dibenzylethylenediamine is presented as a new, efficient, and versatile bidentateligand suitable for the copper catalyzed formation of the C-N bond. This bidentateligand has been demonstrated to facilitate the copper catalyzed cross-coupling reactions of aryl iodides with amides to afford the desired products in good to excellent yields.

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

The reaction of trichloro- and tribromoacetic acids with some imines (the derivatives of aromatic aldehydes and aliphatic as well as some aromatic amines) has been investigated. It has been found that these acids when heated in an organic solvent react with the imines with evolution of carbon dioxide and in the majority of cases the formation of 1,1,1,-trihalogeno-2-aminoethane derivatives in good

rise to di-nuclear ortho-metalated cobalt(II) complex12 through C–Cl bond activation while the reaction of 5 with Co(PMe3)4 delivered bis-chelated cobalt(I) complex 11 through both C–Cl and C–H bond activation. The structures of complexes 3, 4, 8, 9, 11 and 12 were determined by X-ray single crystal diffraction. The catalytic activity of bis-chelated cobalt(I) complex 11 as catalyst for C,C-coupling
