Chemical Research Letters, April 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 66-77-3, Name is 1-Naphthaldehyde, molecular formula is C11H8O, Category: isothiazole, belongs to isothiazole compound, is a common compound. In a patnet, author is Kalogirou, Andreas S., once mentioned the new application about 66-77-3.
Ring transformation of readily prepared (4-chloro-5H-1,2,3-dithiazol-5-ylidene)acetonitriles afford 3-haloisothiazole-5-carbonitriles in good to excellent yields. The transformation can be mediated using HBr (g), HCl (g) or BnEt3NCl. Mechanisms for the transformations are discussed, together with rationalizations for the formation of side products. Furthermore, single crystal X-ray structures are provided for (Z)-2-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)acetonitrile and (E)-2-bromo-2-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)acetonitrile confirming the stereochemistry of the exocyclic ethene bond.
Each elementary reaction can be described in terms of its molecularity, the number of molecules that collide in that step. If you are hungry for even more, make sure to check my other article about 66-77-3, Category: isothiazole.
