Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: 5-Bromobenzothiazole, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 768-11-6, in my other articles.
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. 768-11-6, Name is 5-Bromobenzothiazole, molecular formula is C7H4BrNS. In a Patent£¬once mentioned of 768-11-6, name: 5-Bromobenzothiazole
The invention belongs to the field of medical and chemical intermediate synthesis, provides a based on 1, 3 – propanedithiol as mercapto source synthesis 2 – oxa (thia) and mercaptobenzothiazole azole compound of preparation method, under protection of inert gas, in dimethyl sulfoxide solvent, the oxa (thia) substituted azole with 1, 3 – propanedithiol in the presence of a alkali 120 – 140 C heating and stirring, reaction 12 – 24 hours later, the reaction is cooled down to room temperature, after the acidification is carried out processing to obtain the product. The invention has the reaction condition is simple, functional group compatibility advantages of better and higher yield; the prepared 2 – mercapto-benzoxazole and 2 – mercaptobenzothiazole compound is an important organic synthetic intermediates, raw material in the chemical industry, pesticide, medicine and other field has a very wide application, has strong practical value and social and economic benefits.
