Okamoto, Tsuyoshi published the artcileHalogenation using quaternary ammonium polyhalides. XXXI. Halogenation of thiophene derivatives with benzyltrimethylammonium polyhalides, Quality Control of 111865-47-5, the publication is Bulletin of the Chemical Society of Japan (1991), 64(8), 2566-8, database is CAplus.
The reactions of thiophene derivatives with PhCH2Me3N+ ICl4–, PhCH2Me3N+ Br3–, and PhCH2Me3N+ ICl2– (I) in AcOH or in AcOH-ZnCl2 under mild conditions gave chloro-, bromo-, and iodo-substituted thiophene derivatives, resp., in satisfactory yields. Thus, 3-methylthiophene was treated with I and ZnCl2 in AcOH at room temperature to give 92% 2,5-diiodo-3-methylthiophene (II).
Bulletin of the Chemical Society of Japan published new progress about 111865-47-5. 111865-47-5 belongs to bromides-buliding-blocks, auxiliary class Benzenes, name is Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, and the molecular formula is C10H16Br3N, Quality Control of 111865-47-5.
