Iodine‐Promoted Synthesis of Cyanamides in Aqueous Media and Their Synthetic Application

Abstract

AbstractWe have established an effective one‐pot construction of arylcyanmides and o‐halo arylcyanamides under metal‐free conditions with water at room temperature. Here we have used molecular iodine as a desulfurizing agent. During our standardization study, we could find the desired product in good yields using surfactant (1 % TPGS‐750‐M) and additive (NaOH). Library of aryl isothiocyanates readily converted into their respective desired products 2 a–j in 90–97 % yields. Similarly, o‐halo arylisothiocyanates carried out the reaction to give their respective halo cyanamides in good yields. Further, tetrazole compounds have also been constructed from cyanamides through click‐reaction under moderate reaction conditions.
