《Synthesis of 2-Arylbenzoselenazoles from Se-mediated Redox Condensation of 2-Chloronitrobenzene and Arylmethyl Chlorides》 was written by Gan, Haifeng; Cao, Mengru; Wu, Hongli. Formula: C7H6Cl2 And the article was included in ChemistrySelect on April 13 ,2020. The article conveys some information:
A selenium-mediated redox condensation of 2-chloronitrobenzenes 2-Cl-RC6H3NO2 (R = H, 4-Me, 5-F, 5-CF3, etc.) and arylmethyl chlorides R1CH2Cl (R1 = Ph, naphthalen-1-yl, pyridin-3-yl, etc.) to obtain 2-arylbenzoselenazoles I (R2 = H, 6-Me, 5-F, 5-Br, etc.) has been realized under metal-free condition. The reactions proceeded in moderate-to-good yields with good functional compatibility and gram-scale achievement. Primarily mechanistic investigation suggested that key intermediate Bn(Se)nBn II, was first isolated and confirmed by NMR. After reading the article, we found that the author used 3-Chlorobenzylchloride(cas: 620-20-2Formula: C7H6Cl2)
3-Chlorobenzylchloride(cas: 620-20-2) has been used in the reaction of 3-methoxybenzyl chloride and ethyl 4-bromobenzoate in pure water, using zinc dust and a Pd catalyst.Formula: C7H6Cl2
