A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 136411-21-7, Name is 5-Bromo-4-(trifluoromethyl)thiazol-2-amine, molecular formula is C4H2BrF3N2S. In a Article，once mentioned of 136411-21-7, name: 5-Bromo-4-(trifluoromethyl)thiazol-2-amine
Treatment of 2-trifluoroacetamido-4-(trifluoromethyl)thiazole with two equivalents of n-butyllithium at -78 deg C produced the thiazole dianion 5 in situ, which reacted preferentially at the 5-position with a variety of electrophiles.These electrophiles include: an aldehyde, ketone, chloroformate, acid chloride, phosphorus oxychloride, silicon chloride, and disulfide.Dianion 5 also combined with dibromodifluoromethane at -98 deg C to give the corresponding 5-(bromodifluoromethyl)thiazole 7, which is an unusual reaction for an aromatic or heteroaromatic system.Compound 7 was converted to a 4,5-bis-(trifluoromethyl)thiazole 8 using tetrabutylammonium fluoride.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: 5-Bromo-4-(trifluoromethyl)thiazol-2-amine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 136411-21-7, in my other articles.
