Reactions of C60 with α-Silylamine Derivatives: Two Types of [3+2] Addition of Azomethine Ylides to C60
Thermal [3+2] cycloaddition of C60 with α-silylamine derivatives proceeds smoothly under neutral conditions to afford fullerene-fused pyrrolidines and 1-pyrrolines in moderate to good yields. The new methods are effective for constructing fullerene derivatives containing bulky aryl-substituents.
