Crowned Fullerenes C 60 reacts with [15]crown‐5‐substituted diphenylcarbene precursors to give the corresponding benzo‐crowned methano‐fullerenes 7 , which were isolated preparatively and characterized. Two isomers 7a and 7b , which equilibrate to 7a upon heating, were detected by HPCL and separated. The [15]crown‐5‐, [18]crown‐6‐, and bis[15]crown‐5‐substituted hydrazones 3b—d have been prepared. The X‐ray structure analysis of the crowned hydrazone 3b shows distinct hydrogen bonding patterns between NH‐ and crown oxygen atoms in dimer‐type arrangements.
