Calixcorrole

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

We recently reported that DDQ-mediated oxidative coupling of pyrrole to a free-base meso-triarylcorrole in dichloromethane at room-temperature results in the near-instantaneous formation of pyrrole-appended isocorroles. Herein we report that the use of refluxing dichloromethane and longer reaction times results in the oxidative addition of a second molecule of pyrrole, affording a novel isoporphyrinoid macrocycle calixcorrole in up to 47% yield.
