Abstract

Cyanamides (RR′N–C N) are important intermediates in the synthesis of herbicides 1 and key precursors in the synthesis of N-alkyl or N-aryl imides. 2 They also exhibit apparent tumor growth inhibition activity 3 except for being a sole synthetic intermediate. The wide applications of cyanamides result in the development of many reagents for their synthesis. 4, 5, 6 and 7 Traditional method for the preparation of cyanamides is achieved by the reaction of gaseous cyanogen ...
