Abstract

The azacyclobutane structure is introduced into C60 fullerene using a photochemical reaction with formamidines. Three azetidinofullerenes (2c–2e) were synthesized; their molecular structures were characterized using 1H, 13C, and 2D NMR, matrix-assisted laser desorption ionization (MALDI) mass spectrometry, visible spectroscopy, and electrochemistry. Single crystal X-ray crystallographic analysis of 2e reveals a unique strained four-membered ring including nitrogen atom attached on the fullerene cage. © 2011 Wiley Periodicals, Inc.
