Direct conversion of azides to carbamates and sulfonamides using Fe/NH4Cl: effect of sonication was written by Chandrasekhar, S.;Narsihmulu, Ch.. And the article was included in Tetrahedron Letters in 2000.Computed Properties of C11H14ClNO2 This article mentions the following:
A simple, direct and effective conversion of azides to carbamates and sulfonamides is achieved using Fe/NH4Cl in MeOH. The influence of ultrasonication and direct application in solution-phase combinatorial chem. are also studied by developing a 6×4 matrix library. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Computed Properties of C11H14ClNO2).
tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Computed Properties of C11H14ClNO2
