12via thermaldecomposition of the corresponding pyrazolines 11 is reported. In the diastereomers 12 the protons of the monoalkylated methylene bridge are located above a six-membered ring and the bulkier alkyl groups above a five-memberedring. The corresponding methanofullerenes were not detected and the diastereomeric fulleroids 13 with the methylene bridge proton above a five-memberedring are formed
