New discoveries in chemical research and development in 2021, Chemistry involves the study of all things chemical – chemical processes, how they change and how they react in certain situations. 66-77-3, Name is 1-Naphthaldehyde, SMILES is O=CC1=C2C=CC=CC2=CC=C1, in an article , author is Kalogirou, Andreas S., once mentioned of 66-77-3, Safety of 1-Naphthaldehyde.
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, Safety of 1-Naphthaldehyde.
