《Condensed Thiophenes and Selenophenes: Thionyl Chloride and Selenium Oxychloride as Sulfur and Selenium Transfer Reagents》 was written by Amaresh, Ramiya R.; Lakshmikantham, M. V.; Baldwin, Jeffrey W.; Cava, Michael. P.; Metzger, Robert M.; Rogers, Robin D.. HPLC of Formula: 425394-71-4 And the article was included in Journal of Organic Chemistry on April 19 ,2002. The article conveys some information:
3,4-Bis(cyanomethyl) substituted thiophenes reacted with thionyl chloride in the presence of base to give dicyano substituted thieno[3,4-c]thiophenes. The use of selenium oxychloride furnished the corresponding cyano substituted seleno[3,4-c]thiophene. 1,2-Phenylenediacetonitriles gave the corresponding cyano substituted benzo[c]thiophenes and benzo[c]selenenophenes, resp., upon reaction with thionyl chloride and selenium oxychloride in the presence of base. In the experimental materials used by the author, we found 1-Bromo-4-chloro-2,3-dimethylbenzene(cas: 425394-71-4HPLC of Formula: 425394-71-4)
1-Bromo-4-chloro-2,3-dimethylbenzene(cas: 425394-71-4) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. HPLC of Formula: 425394-71-4 However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
