Small molecules such as dihydrogen (H 2 ), carbon dioxide (CO and dinitrogen (N ) are ubiquitous in nature have important industrial environmental applications. This review article discusses the activation of these small utilizing transition metal complexes because transformation into value added products is a topic current research due to economic importance. The also interesting interaction between with their mechanisms, formation hydride for H , formate CO ammonia production from N . compounds using recently considered more affordable method synthesizing new organic through catalytic processes. Therefore, this aspires provide insights boosting complex design improved reactivity greater practicality situations by combining most recent knowledge.

Rhenium(I) tricarbonyl complexes fac-[Re(bpy)(CO)3(L)]n+ are the classic examples of self-sensitized photocatalysts capable dual roles light absorption and catalysis. In this work, a series dicationic halido or tricationic solvento fac-[Re(bpy2+)(CO)3X]n+ (PF6)n (where X = Cl- I- (n 2), CH3CN 3) bpy2+ is bipyridine modified by two -CH2-(NMe3)+ tetra-alkylammonium cations) have been investigated as sensitized CO2 reduction photocatalysts. Four structural isomers differing in cation position tested N,N'-dimethylacetamide solvent (DMA) using 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzimidazole (BIH) electron donor, cationic pendants has significant impact on catalyst turnover number quantum efficiency (ϕ). Up to 455 turnovers CO high photon (ϕCO) 22% achieved. Time-resolved infrared spectroscopy theoretical calculations were used characterize catalytic cycle including ligand exchange between one-electron reduced (OER) species well binding putative two-electron (TER) species. The CO2-reactive TER was formed disproportionation intramolecular transfer forms OER indicated formation fully oxidized concurrent with binding. When [Ru(bpy)3]2+ sensitizer, durability improved, selectivity toward formate increased 3.3:1 over (total TON 1370) due acidification reaction, which promotes hydride intermediate, BIH consumed deprotonated.
