The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.3581-87-1, Name is 2-Methylthiazole, molecular formula is C4H5NS. In a Article，once mentioned of 3581-87-1, category: thiazole
2-Methyl-1,3-thiazole, 2,4-dimethyl-1,3-thiazole, 2,4,5-trimethyl-1,3- thiazole, 2,4,5-trimethyl-1,3-oxazole, 2-methyl-1,3-benzoxazole and 2-methyl-1,3-benzothiazole were each treated with benzoyl chloride in acetonitrile containing triethylamine to give the corresponding (Z)-2-(heterocyclic)-1-phenylvinyl benzoates. Base hydrolysis of these vinyl benzoates gave the corresponding 2-(heterocyclic)-1-phenylethenols, which exist in both keto and enol tautomeric forms. These tautomers were used as starting materials for the syntheses of fused-ring heterocycles. The reactivity of the keto-enol tautomers depends on the nature of the heteroatom and the substituents that are present on the ring. Each tautomeric pair reacts with dimethyl acetylenedicarboxylate (DMAD) in methanol to give the 5,6-ring-fused 8-benzoyl-5-oxo-5H-thiazolo- and 8-benzoyl-5-oxo-5H-oxazolopyridinecarboxylate, 4-benzoyl-1-oxo-1H-pyrido[2,1-b]benzoxazolecarboxylate and 4-benzoyl-1-oxo-1H- pyrido[2,1-b]benzothiazolecarboxylate derivatives. Two novel 5,7-ring-fused compounds, tetramethyl 9-benzoyl-2,3-dimethyl-5,6-dihydrothiazolo[3,2-a]azepine- 5,6,7,8-tetracarboxylate and its oxazole analogue, were also obtained when the tautomers formed from 2,4,5-trimethyl-1,3-thiazole and 2,4,5-trimethyl-1,3- oxazole, respectively, were treated with DMAD. Reactions of the tautomers with methyl propiolate did not, however, give satisfactory results. Georg Thieme Verlag Stuttgart. New York.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: thiazole, you can also check out more blogs about3581-87-1
