Reactivity of the N-Methylene-5,8-didehydroisoquinolinium Triradicai Ion

摘要

Triradicals contain three electrons in three orbitals that are similar in energy.As a result,these species have several low-lying electronic states.This characteristic makes triradicals fascinating species to study.However,most prior studies of organic triradicals have been computational in nature because of the difficulty in studying such highly reactive species experimentally.pi,pi,pi-Polyarylmethyl and calixarene triradicals have been characterized via ESR,NMR,and UV-vis spectroscopy and cyclic voltammetry by Rajca and Rajca.
