Preparation and Molecular Structure of Pyrrolinenitroxide Radical Urea

Abstract

Abstract: The title compound was obtained as a by product in a contraction reaction by using DICas a coupling reagent. X-ray diffraction shows the title compound is a pyrrolinenitroxide radical urea. Two crystallographically independent molecules possess different conformations but the identical bond distances and angles. Based on the molecular structure a possible reaction mechanism is proposed for the reaction of DICand carboxylic acid.

Key words: Pyrrolinenitroxide radical, Coupling reagent, N′N Diisopropylcarbondiimide, Molecular structure
