Abstract
A new and efficient method has been designed to prepare 2,2'-arylene-substituted bis(4H-3,1-benzoxazin-4-one) derivatives by using the mixture of cyanuric chloride and N,N-dimethylformamide in a microwave-assisted reaction. The method used and presented here has good rate enhancement and excellent yields.
