An efficient strategy which integrates visible-light-induced iminyl-radical formation with carboimination of unactivated alkenes has been developed for the easy access of densely functionalized pyrroline derivatives With fac-[Ir(ppy)3] as photoredox catalyst, the acyl oximes were converted into iminyl radical intermediates by one electron reduction, and evolve through a cascade of intramol. cyclization and intermol. carbon radical trapping to give the functionalized pyrrolines. The utilization of silyl enol ethers as coupling partners not only allows the introduction of synthetically useful ketone functionalities but also renders catalyst regeneration without any external reductants. This protocol is characterized by its mild reaction conditions and the tolerance of a broad range of functionalities. In the experiment, the researchers used many compounds, for example, N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide (cas: 116332-61-7Quality Control of N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide).
N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide (cas: 116332-61-7) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Quality Control of N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide
