Liang, Hao; Zhu, Guoxun; Pu, Xiaoyun; Qiu, Liqin published their research in Organic Letters in 2021. The article was titled 《Copper-Catalyzed Enantioselective C-H Arylation between 2-Arylindoles and Hypervalent Iodine Reagents》.Application In Synthesis of 4-Chloro-2-iodoaniline The article contains the following contents:

The copper-catalyzed enantioselective C-H arylation between 2-arylindoles I [R1 = naphthalen-1-yl, thiophen-2-yl, 4-chlorophenyl, etc.; R2 = H, 5-Cl, 6-Br, 5-(4-(trifluoromethoxy)phenyl)] and hypervalent iodine reagents II (R3 = 5-Me, 5-Cl, 3-Cl-5-Me, 5-OMe) has been successfully developed, which provides a convenient and economical route to the highly atroposelective synthesis of axially chiral indole derivatives with a 2-aryl structures III (up to 99% ee). D. functional theory calculations and wave function anal. show that the key “”sandwich”” intermediate leads to high enantioselectivity of the reaction.4-Chloro-2-iodoaniline(cas: 63069-48-7Application In Synthesis of 4-Chloro-2-iodoaniline) was used in this study.

4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. To avoid the problem of multiple alkylation, methods have been devised for “blocking” substitution so that only one alkyl group is introduced. The Gabriel synthesis is one such method; it utilizes phthalimide, C6H4(CO)2NH, whose one acidic hydrogen atom has been removed upon the addition of a base such as KOH to form a salt.Application In Synthesis of 4-Chloro-2-iodoaniline

The article was titled 《Photoinduced Radical Cascade Cyclization: A Metal-Free Approach to Access Difluoroalkylated Dioxodibenzothiazepines》.Reference of 4-Chloro-2-iodoaniline The article contains the following contents:

A simple and mild photoredox catalytic approach to access difluoroalkylated dioxodibenzothiazepines I [R1 = Me, Bz, cyclohexyl, etc.; R2 = CO2Et, C(O)NEt2, P(O)(OEt)2, etc.; R3 = H, Me, Ph, etc.; R4 = H, F, Cl, Br; R5 = H, Me, F, Cl, Br; R6 = H, Me, Cl, etc.] in high regioselectivity via radical cascade cyclization was described. In contrast to previous methods, this strategy did not involved the use of transition-metal catalysts and avoided the potential disadvantages of inevitable toxicity and the tedious removal process of metal catalysts. The com. available and inexpensive CF2 precursors, wide substrate scope and mild reaction conditions demonstrated the practicability of this approach. In the experiment, the researchers used 4-Chloro-2-iodoaniline(cas: 63069-48-7Reference of 4-Chloro-2-iodoaniline)

4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.Reference of 4-Chloro-2-iodoaniline
