In some cases, the catalyzed mechanism may include additional steps.In a article, 2213-63-0, molcular formula is C8H4Cl2N2, introducing its new discovery.
Synthesis and properties of 2,3-heteroannulated thiochromones – hetero analogs of thioxanthone
[Figure not available: see fulltext.] This article provides generalized and systematic data on the synthesis and some properties of 2,3-heteroannulated thiochromones that can be viewed as hetero analogs of thioxanthone. The main emphasis is on various methods for the preparation of compounds that are arranged according to the starting material structures. Analysis of literature data shows that the most valuable and commonly used starting materials for obtaining hetero analogs of thioxanthone are substituted thiophenols, 2(3)-functionalized thiochromone derivatives, as well as 4-hydroxydithiocoumarins and (?-haloaroyl)thioacetamides. Azathioxanthones (thiochromenopyridines) are the most studied examples of 2,3-heterothiochromones. This review is concluded with some basic facts about 2,3-carboannulated thiochromones. A total of 99 references are given.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2213-63-0 is helpful to your research. Reference of 2213-63-0
