A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 521284-22-0, Name is (R)-2-((4-Aminophenethyl)amino)-1-phenylethanol hydrochloride, molecular formula is C16H21ClN2O. In an article, author is Oda, Ryoga,once mentioned of 521284-22-0, Recommanded Product: 521284-22-0.
Nucleophilic substitutions of benzylic alcohols with sulfamides were achieved using an FeCl3 Lewis acid catalyst in MeNO2. It was necessary to adjust the reaction conditions to obtain efficient yields depending on the stability of the carbocation intermediates. The reaction could easily be performed, and it was revealed that a variety of diarylmethanols and benzylic alcohols were applicable to the reaction, irrespective of the type and position of the substituents. The sulfamide moieties were easily deprotected and converted into amine groups.
