Abstract

This letter reports a new, two-step synthesis of symmetrical diarylamincs from 1,3-dinitroproparics, by their reaction with acrolein under basic conditions (Al2O3, neat), followed by aromatisation of the obtained 2,4-dinitrocyclohexanols, through their treatment with four equivalents of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), in acetonitrile as a solvent. and warming overnight at 60 degrees C.
