Abstract

An available diaminofullerene 1 was used as a substrate in photochemical reactions with other secondary amines, namely N-substituted piperizines 2a-b for reverse reaction. 3A was treated with an excess of N-(2-pyridyl) piperazine under photochemical conditions. It was shown that amine groups attached to the fullerene cage can be reversibly replaced by residues of other amines under irradiation with visible lights. Studies revealed that this interconversion of 1,4-diaminofullerenes proceeds with the same efficiency at room temperature even in the absence of light and air. It can be expected that the reported novel reaction will find many applications, particularly when a wider range of nucleophiles is introduced in the reactions with 1,4-diamino-fullerenes.
