The mechanochemical cascade reaction of [60]fullerene with 3-benzylidene succinimides, diethyl 2-benzylidene succinate, or succinonitrile in the presence an inorganic base has been investigated under solvent-free and ball-milling conditions. This protocol provides expedient method to afford various [60]fullerene-fused cyclopentanes, showing advantages good substrate scope, short time, ambient Furthermore, representative fullerene products have applied inverted planar perovskite solar cells as efficient cathode interlayers.
