Here, a copper(I)-catalyzed synthetic method for the efficient site-selective C(sp3)-H bond chlorination of ketones, (E)-enones and alkylbenzenes by dichloramine-T at room temperature were reported. A key feature of the broad substrate scope is tolerance to unsaturation, which would normally pose an immense challenge in chemoselective aliphatic C-H bond functionalization. By unlocking dichloramine-T’s potential as a chlorine radical atom source, the product site-selectivities achieved were among the most selective in alkane functionalization and should find widespread utility in chem. synthesis. This was exemplified by the late-stage site-selective modification of a number of natural products and bioactive compounds and gram-scale preparation and formal synthesis of two drug mols. In the experiment, the researchers used many compounds, for example, N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide (cas: 116332-61-7Electric Literature of C10H10F3NO2).
N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide (cas: 116332-61-7) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Electric Literature of C10H10F3NO2
