Benzylamine promoted direct C-H arylation of arenes and heteroarenes excitation with heat or light.

Carbon-halogen bond cleavage in aryl halides through single electron transfer (SET) is a crucial step in radical-based cross-coupling reactions. Accomplishing such cleavage using an organic system without the assistance of any transition metal-based catalyst is highly challenging. In recent years, combining organic molecules and a base has served as a unique system for SET-mediated carbon-halogen bond cleavage.

Phenalenyl-ruthenium synergism for effectual catalytic transformations of primary amines to amides.

The synthesis of amides holds great promise owing to their impeccable contributions as building blocks for highly valued functional derivatives. Herein, we disclose the design, synthesis and crystal structure of a mixed-ligand ruthenium(II) complex, [Ru(η-Cym)(O,O-PLY)Cl], (1) where Cym = 1-isopropyl-4-methyl-benzene and O,O-PLY = deprotonated form of 9-hydroxy phenalenone (HO,O-PLY). The complex catalyzes the aerobic oxidation of various primary amines (RCHNH) to value-added amides (RCONH) with excellent selectivity and efficiency under relatively mild conditions with common organic functional group tolerance.

Ligand-metal cooperativity in quinonoid based nickel(II) and cobalt(II) complexes for catalytic hydrosilylative reduction of nitriles to amines: electron transfer and mechanistic insight.

The sustainable production of privileged amines by the catalytic reduction of nitriles with an inexpensive silane polymethylhydrosiloxane (PMHS) holds great promise to replace conventional synthetic routes that have limited applicability and involve the use of expensive metal catalysts. The use of late 3d-metal complexes provides an excellent platform for the rational design of inexpensive catalysts with exquisite control over their electronic and structural features through metal-ligand cooperativity. In this context, we have realistically designed two complexes based on nickel(II) and cobalt(II) with a redox-active imino--benzoquinonato ligand.
