《Facile Preparation of Benzoxazoles from S8-Promoted Cyclization of 2-Nitrophenols with Arylmethyl Chloride》 was published in ChemistrySelect in 2019. These research results belong to Gan, Haifeng. Recommanded Product: 3-Chlorobenzylchloride The article mentions the following:
A simple, metal-free methodol. has been obtained for the preparation of 2-arylbenzoxazoles I (R = H, 6-Me, 5-NHC(O)CH3, etc.; R1 = Ph, naphthalen-2-yl, pyridin-4-yl, etc.) from 2-nitrophenols 2-NO2-R2 -C6H3OH (R = H, 5-Me, 4-F, etc.) and arylmethyl chlorides R1CH2Cl via an elemental sulfur-promoted cyclization reaction. The reactions proceeded in moderate to good yields, and gram-scale is applicable. After reading the article, we found that the author used 3-Chlorobenzylchloride(cas: 620-20-2Recommanded Product: 3-Chlorobenzylchloride)
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.Recommanded Product: 3-Chlorobenzylchloride
