In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Derivatives of benzothiazole. II. Obtaining 2-chlorobenzothiazole and some of its derivatives, published in 1937, which mentions a compound: 2407-11-6, Name is 2-Chloro-6-nitrobenzo[d]thiazole, Molecular C7H3ClN2O2S, Recommanded Product: 2-Chloro-6-nitrobenzo[d]thiazole.
cf. C. A. 32, 160.5. Nitration of 2-mercaptobenzothiazole (I) gives 70% of 6-nitro-2-mercaptobenzothiazole, m. 226°. Reduction of this with H2S gives 75% of the corresponding amine, m. 260-1° and this, by diazotization and treatment with Cu2Cl2 and HCl gives 6-chloro-2-mercaptobenzothiazole (II), m. 244-5°. In an analogous way the 6-I derivative, m. 233-4°, is obtained. By diazotization of 2-aminobenzothiazole, 25% of 2-chlorobenzothiazole (III) is obtained, but if I is heated with PCl5 in POCl3 or PSCl3 at 100° until no more HCl is evolved, 55% of III, b. 248°, is obtained. At the same time a small amount of dibenzothiazolyl 2,2′-monosulfide (IV), m. 106°, is obtained. If the reaction temperature is raised, more IV and less III are formed. Nitration of IV gives a mixture of 6-nitro- and 6,6′-dinitrodibenzothiazolyl 2,2′-monosulfides, m. 142° and 281-2°, resp. Higher nitration temperature favors formation of the dinitro compound Nitration of III gives 83% of 6-nitro-2-chlorobenzothiazole, m. 192°. The same compound is obtained from 6-nitrobenzothiazolyl 2,2′-monosulfide and PCl5, but only in 5% yield. A poor yield of product is also obtained when II is treated with PCl5. Thus, side reactions occur to a very great extent when PCl5 reacts with derivatives of 2-mercaptobenzothiazole.
This literature about this compound(2407-11-6)Recommanded Product: 2-Chloro-6-nitrobenzo[d]thiazolehas given us a lot of inspiration, and I hope that the research on this compound(2-Chloro-6-nitrobenzo[d]thiazole) can be further advanced. Maybe we can get more compounds in a similar way.
