We will report on a variety of new arylation reactions leading to well defined oligoadducts of the heteofullerene C59N. These adducts contain an integral pyroll subunit. On the way the full arylation a variety of mono- and bishydrides could be isolated as well. All new compounds were fully characterized including x-ray crystallography. Based on the experimental data a convinving reaction mechanism describing the formation of these new fullerene adducts was proposed.
