Iodine mediated an efficient and greener thiocyanation of aminopyrimidines by a modification of the Kaufmann’s reaction
摘要:
A new, safe, and efficient methodology for the thiocyanation of some aminopyrimidine derivatives has been implemented. The thiocyanation reactions proceeded at room temperature with high yields and selectivity. This route is a less toxic alternative to other common thiocyanation techniques because it uses molecular iodine as a halogen source, which is less reactive and easier to handle than chlorine or bromine.
