Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 2942-23-6, C7H3Cl2NS. A document type is Article, introducing its new discovery., Recommanded Product: 2,7-Dichlorobenzo[d]thiazole
A convenient synthesis of 2-mercapto and 2-chlorobenzothiazoles is described. The key feature of the synthesis is an exclusive ortho-selective nucleophilic aromatic substitution reaction of ortho-haloanilines with potassium/sodium O-ethyl dithiocarbonate under mild conditions. Subsequent intra-molecular cyclization affords 2-mercaptobenzothiazoles in high yields. The 2-mercaptobenzothiazoles are readily converted to corresponding 2-chlorobenzothiazoles upon treatment with sulfuryl chloride.
