摘要：

An effortless and efficient protocol was developed for the synthesis of N,N'-diarylsubstituted formamidines under environment-friendly conditions. Ultrasonic energy was employed to obtain the desired products in excellent yields with high purity under solvent-free and catalyst-free conditions. Products were purified by the crystallization technique to avoid excess utilization of organic solvents. (C) 2013 Elsevier Ltd. All rights reserved.
