In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Generation of Alkoxyl Radicals by Photoredox Catalysis Enables Selective C(sp3)-H Functionalization under Mild Reaction Conditions, published in 2016, which mentions a compound: 676525-77-2, Name is [Ir(dtbbpy)(ppy)2]PF6, Molecular C40H40F6IrN4P, Computed Properties of C40H40F6IrN4P.
Reported herein is the first visible-light-induced formation of alkoxyl radicals from N-(alkoxy)phthalimides, and the Hantzsch ester as the reductant is crucial for the reaction. The selective hydrogen atom abstraction by the alkoxyl radical enables C(sp3)-H allylation and alkenylation reactions under mild reaction conditions at room temperature Broad substrate variations, including a structurally complex steroid, undergo the C(sp3)-H functionalization reaction effectively with high regioselectivity and chemoselectivity. The synthesis of the target compounds was achieved using 2-[(phenylsulfonyl)methyl]-2-propenoic acid Et ester as a starting material in a reaction with 2-[2-[(4-methylphenyl)methoxy]ethoxy]-1H-isoindole-1,3(2H)-dione [i.e., cyclic N-(alkoxy)imide, phthalimide] derivatives Under optimized conditions tris[2-(2-pyridinyl-κN)phenyl-κC]iridium(1+) um(1+) hexafluorophosphate(1-) [i.e., fac-Ir(ppy)3] was used as a catalyst. The title compounds thus formed included 2-[[(2E)-3-phenyl-2-propen-1-yl]oxy]ethanol derivatives, γ-(2-hydroxyethoxy)-α-(methlyene)benzenebutanoic acid esters,.
