Rapid and efficient synthesis of imidazolines and bisimidazolines under microwave and ultrasonic irradiation

Abstract

Small assemblies of 2-imidazolines and bisimidazolines from appropriate nitriles and ethylenediamine with catalytic amounts of P2S 5 employing a microwave assisted protocol were prepared. Sonication of this system also led to successful synthesis of 2-imidazolines and bisimidazolines. Another advantage of these systems is the ability to carry out large scale reactions. © Springer-Verlag 2007.
