文摘The title compound was obtained as a by product in a contraction reaction by using DIC as 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 DIC and carboxylic acid.
