Corrections are provided for the misuse of the term “”directionality””; the numerical results are unaffected. After reading the article, we found that the author used 2-Fluoro-5-iodopyrimidine(cas: 697300-79-1Application In Synthesis of 2-Fluoro-5-iodopyrimidine)
2-Fluoro-5-iodopyrimidine(cas: 697300-79-1) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Application In Synthesis of 2-Fluoro-5-iodopyrimidine
