Synthesis of 6-substituted 3,4-dihydro-2H-1-benzopyran-2-ones (dihydrocoumarins) via palladium catalyzed coupling reactions was written by Davies, Stephen G.;Pyatt, Dirk;Thomson, Colin. And the article was included in Journal of Organometallic Chemistry in 1990.Synthetic Route of C9H7IO2 This article mentions the following:
6-Alkenyl, 6-alkynyl, and 6-aryl-3,4-dihydrocoumarins have been prepared from 6-bromo-3,4-dihydrocoumarin via palladium-catalyzed coupling reactions. 6-Carbalkoxy- and 6-keto-3,4-dihydrocoumarins have been obtained via palladium-catalyzed carbonylations of 6-bromo- and 6-iodo-3,4-dihydrocoumarins, resp. In the experiment, the researchers used many compounds, for example, 6-Iodochroman-2-one (cas: 128651-99-0Synthetic Route of C9H7IO2).
6-Iodochroman-2-one (cas: 128651-99-0) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Synthetic Route of C9H7IO2
