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. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Related Products of 18437-66-6

The use of simple solid Bronsted acid catalysts to achieve continuous N-Boc deprotection of amines, e.g., tert-Bu 2-oxopiperidine-1-carboxylate without addnl. workup steps has been described. Using THF as the solvent, H-BEA zeolite affords high yields of a variety of aromatic and aliphatic amines, e.g., 2-piperidinone often in residence times of less than a minute at 140°C. The same catalyst/solvent combination is ineffective in batch conditions, due to the much lower temperature of refluxing THF. Boc-protected p-chloroaniline was deprotected with a throughput of 18 mmol p-chloroaniline per h per gcat, sustained over 9 h. The active sites of the zeolite do not appear to be directly associated with the Al framework substitution in the micropores, since partially ion-exchanged Na/H-BEA shows activity similar to H-BEA. The strong Bronsted acid sites (framework [Si(OH)Al]), are likely poisoned by the amine product. Moderate Bronsted acid sites associated with silanol defects near Al on or near the external surface (and not susceptible to Na+-exchange) are presumably the active sites, since they are not poisoned even by more basic aliphatic amines. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Related Products of 18437-66-6).
