The mechanistic investigations of photochemical carbonyl elimination and oxidative addition reactions of (η5-C5H5)M(CO)3, (M = Mn and Re) complexes

“…(i) At the higher-energy band (using the 295 nm light): It is well known that spin-allowed absorption cross-sections are basically larger than those for spin-forbidden excitations. [58][59][60][61][62][63] Moreover, as seen in the le-hand side of Fig. 2, once Mn-S 0 -Rea is absorbed by light with 295 nm, the possibility for the Mn complex relaxing from the singlet FC zone to the triplet region is quite slim, since the excited Mn complex would initially jump to the nearby singlet excited state.…”

Recent advances in the synthesis of pyrroles via multicomponent reactions using arylglyoxals

“…[8][9][10][11][12][13][14] The important pharmaceutical, biological and materials science applications of pyrrole, and its significance as an intermediate in the synthesis of natural products, have led pyrroles to become an important class of heterocyclic compounds in organic chemistry. [14][15][16][17][18][19][20][21] Therefore, due to the manifold pharmaceutical and biological properties of pyrrole derivatives, such as antibacterial, [22][23][24][25][26] anticancer [27][28][29][30][31][32][33] (for the treatment of several types of tumor), antifungal, [34][35][36][37] antiinflammatory, [38][39][40] antiviral, 41,42 antimalarial, 43 antiparasitic, 44 anticholestaemic (Atorvastatin is a drug widely used as a cholesterol-lowering agent), 45 antibiotic, 46 anti-HIV, [47][48][49] antioxidant, [50][51]…”

A Critical Review on Advances in the Multicomponent Synthesis of Pyrroles

“…Heterocyclic molecules are a valuable class of organic compounds which show a broad spectrum of application in medicinal chemistry, 1 biochemistry, 2 photochemistry, 3 material science 4 and environmental science. 5 With the increasing emphasis on eco-friendly chemical synthesis in recent decades, new breakthroughs are needed in the synthesis of heterocyclic compounds so as to avoid the use of hazardous chemicals, catalyst, solvent and techniques.…”
