Abstract
Aromatic aldehydes are condensed with 2,4‐dinitro‐1,5‐dimethylbenzene in a Siegrist type coupling. The reported method features microwave irradiation, solvent‐free conditions, and a catalytic amount of piperidine to give a high yield of the corresponding 1,3‐bisstyryl‐4,6‐dinitrobenzenes within a few minutes.
