Palladium-Catalyzed Intermolecular Coupling of Aryl Chlorides and Sulfonamides under Microwave Irradiation was written by Burton, George;Cao, Ping;Li, Gang;Rivero, Ralph. And the article was included in Organic Letters in 2003.Electric Literature of C9H8ClNO4 This article mentions the following:
An efficient intermol. N-arylation of sulfonamides with aryl chlorides is realized using Pd catalysis. The reaction proceeds under microwave irradiation at 180-200° for 10 min with 2-10 mol % of Pd catalyst in 32-85% isolated yields. In the experiment, the researchers used many compounds, for example, Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2Electric Literature of C9H8ClNO4).
Ethyl 4-chloro-3-nitrobenzoate (cas: 16588-16-2) 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.Electric Literature of C9H8ClNO4
