C60 underwent hetero Diels-Alder reaction with a carbethoxysubstituted 2-aza-1,3-butadiene and trimethylsilylthio-substituted 1,3-diaza-1,3-butadiene (which possibly reacts as trimethylsilylamino-substituted 1-thia-3-aza-1,3-butadiene) to give C60 derivatives fused with cyclic amino acid and thiourea, respectively. The latter was explained to arise under equilibrated conditions.
