Katritzky salts were used as the alkyl radical precursors with the insertion of sulfur dioxide under photoredox catalysis. This transformation first enables direct generation of various alkylsulfonyl radicals by photoinduced single electron reduction, leading to diverse dialkyl sulfones in good to excellent yields. A radical pathway was proposed under visible-light induced conditions with the insertion of sulfur dioxide. In the experiment, the researchers used tert-Butyl 4-aminopiperidine-1-carboxylate(cas: 87120-72-7Computed Properties of C10H20N2O2)
tert-Butyl 4-aminopiperidine-1-carboxylate(cas: 87120-72-7) belongs to anime. Acylation is one of the most important reactions of primary and secondary amines; a hydrogen atom is replaced by an acyl group (a group derived from an acid, such as RCOOH or RSO3H, by removal of ―OH, such as RC(=O)―, RS(O)2―, and so on). Reagents may be acid chlorides (RCOC1, RSO2C1), anhydrides ((RCO)2O), or even esters (RCOOR′); the products are amides of the corresponding acids.Computed Properties of C10H20N2O2
