New Effective Synthetic Method for Preparation of N,N-Dichlorocarbamates

Abstract

A rapid, efficient, economical, and easy-to-scale method for the effective conversion of carbamates to corresponding N,N-dichlorocarbamates by using sodium hypochlorite in acidic medium has been described. N,N-Dichlorocarbamates were obtained in quantitative yield through a simple workup in reduced reaction time.

Keywords:

• Acidic medium
• sodium hypochlorite
• substituted N,N-dichlorocarbamates
