Herein authors report simple, efficient, and economically affordable metal-ligand cooperative strategies for synthesizing quinolines and quinazolin-4(3H)-ones via dehydrogenative functionalization of alcs. Various polysubstituted quinolines and quinazolin-4(3H)-ones were prepared in good yields via dehydrogenative coupling of readily available alcs. with ketones and 2-aminobenzamides, resp. under air using a well-defined Fe(II)-catalyst, ([FeL1Cl2]) bearing a redox-active azo-aromatic pincer 2-((4-chlorophenyl), (diazenyl)-1,10-phenanthroline) (L1). Control experiments and mechanistic investigation disclose that the one-electron reduced mono-anionic species [1]- bearing an iron-stabilized azo-anion radical ligand catalyzes these reactions. Both iron and the redox-active arylazo ligand participate synergistically during the different steps of these catalytic reactions. In the experimental materials used by the author, we found 1-Thiophen-2-yl-ethanone(cas: 88-15-3SDS of cas: 88-15-3)
1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Reflecting their high stabilities, thiophenes arise from many reactions involving sulfur sources and hydrocarbons, especially unsaturated ones. Thiophenes are classically prepared by the reaction of 1,4-diketones, diesters, or dicarboxylates with sulfidizing reagents such as P4S10 such as in the Paal-Knorr thiophene synthesis.
