Visible-Light-Mediated Alkylation of Thiophenols via Electron Donor-Acceptor Complexes Formed between Two Reactants was written by Cai, Yi-Ping;Nie, Fang-Yuan;Song, Qin-Hua. And the article was included in Journal of Organic Chemistry in 2021.Category: piperidines This article mentions the following:
A metal-free, photocatalyst-free, photochem. system was developed for the direct alkylation of thiophenols ArSH (Ar = 4-chlorophenyl, naphthalen-2-yl, pyridin-4-yl, 1,3-benzothiazol-2-yl, etc.) via electron donor-acceptor (EDA) complexes (KEDA = 145 M-1) associated between two reactants, N-hydroxyphthalimide esters I [R = 3-oxobutyl, cyclohexyl, 1-[4-(2-methylpropyl)phenyl]ethyl, 1-[(tert-butoxy)carbonyl]piperidin-4-yl, etc.] as acceptors and thiophenol anions as donors, in the presence of a tertiary amine to give corresponding aryl alkyl sulfides RS(Ar). The EDA complexes in the reaction system have broad range of visible light absorption (400-650 nm) and can trigger the reaction effectively under sunlight. In the experiment, the researchers used many compounds, for example, 1-(tert-Butyl) 4-(1,3-dioxoisoindolin-2-yl) piperidine-1,4-dicarboxylate (cas: 1872262-73-1Category: piperidines).
1-(tert-Butyl) 4-(1,3-dioxoisoindolin-2-yl) piperidine-1,4-dicarboxylate (cas: 1872262-73-1) belongs to piperidine derivatives. Piperidine is a metabolite of cadaverine, a polyamine found in the human intestine. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.Category: piperidines
