Abstract

The tether-directed method was firstly applied to the biscyclopropanation of [60] fullerene via the addition–elimination reaction of bis (sulfonium ylide) s to give bis (formylmethano)[60] fullerenes with satisfactory regio-and stereoselectivity. The equatorial-bisadduct thus obtained was used for the polycondensation with an aromatic diamine to afford the corresponding pearl-necklace polyimine with satisfactorily high degree of polymerization.
