—— | 2,5-Dibromo-3-(8-bromooctyl)thiophene | 1267610-21-8 | C12H17Br3S | 433.045 |
The synthesis is reported of 4-[ω-(3-thienyl)alkyl]pyridine (2), 4-[ω-(3-thienyl)alkyl]-2,2′- bipyridine (3) and 4-methyl-4'-[ω-(3-thienyl)alkyl]-2,2′-bipyridine (4), where the length of the alkyl chain is varied (n = 2, 5, 7, 9, 11). The synthetic methodology involved the reaction of the 3-(ω- bromoalkyl ) thiophen with the anions derived from 4-methylpyridine, 4-methyl-2,2′-bipyridine or 4,4′-dimethyl-2,2′-bipyridine by lithiation . The n.m.r. (1H and 13C) and electronic spectral characteristics of the compounds are discussed.
