COA of Formula: C5H11NO3In 2021 ,《Hydroxylamine-Derived Reagent as a Dual Oxidant and Amino Group Donor for the Iron-Catalyzed Preparation of Unprotected Sulfinamides from Thiols》 was published in Angewandte Chemie, International Edition. The article was written by Chatterjee, Sayanti; Makai, Szabolcs; Morandi, Bill. The article contains the following contents:
An iron catalyzed reaction for the selective transformation of thiols (-SH) to sulfinamides (-SONH2) by a direct transfer of -O and free -NH2 groups has been developed. The reaction operates under mild conditions using a bench stable hydroxylamine derived reagent, exhibits broad functional group tolerance, is scalable and proceeds without the use of any precious metal catalyst or addnl. oxidant. This novel, practical reaction leads to the formation of two distinct new bonds (S=O and S-N) in a single step to chemoselectively form valuable, unprotected sulfinamide products. Preliminary mechanistic studies implicate the role of the alc. solvent as an oxygen atom donor. The experimental part of the paper was very detailed, including the reaction process of N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3COA of Formula: C5H11NO3)
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.COA of Formula: C5H11NO3
