Efficient and Novel Synthesis of N‐Aryl‐N′‐ethoxycarbonylthiourea and Arene‐bis‐ethoxycarbonylthiourea Derivatives Catalyzed by TMEDA

Abstract

A series of N‐aryl‐N′‐ethoxycarbonyl thioureas and arene‐bis‐ethoxycarbonylthiourea derivatives have been synthesized in good to excellent yields under the TMEDA catalyzed conditions at room temperature.

Keywords:

• Ethyl chloroformate
• Thiocyanate
