Nano-ferrous ferric oxide (nano-Fe3O4). Powerful, reusable, and stable catalyst for N-Boc protection of amines was written by Zolfigol, Mohammad Ali;Moosavi-Zare, Ahmad Reza;Moosavi, Parvin;Khakyzadeh, Vahid;Zare, Abdolkarim. And the article was included in Comptes Rendus Chimie in 2013.Name: tert-Butyl (4-chlorophenyl)carbamate This article mentions the following:
Nano-ferrous ferric oxide (nano-Fe3O4) efficiently catalyzed N-boc protection of amines in high yields and acceptable reaction times. Nano-Fe3O4 was applied as an efficient, green, heterogeneous and reusable magnetite catalyst. Clean reaction, simple purification, short reaction time and high yield were some other advantages of this compound In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Name: tert-Butyl (4-chlorophenyl)carbamate).
tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Name: tert-Butyl (4-chlorophenyl)carbamate
