Selective deletion of one carbon atom from C60 through benzylamine mediated reactions

Org. Chem. Front., 2024, Advance Article
DOI: 10.1039/D4QO00449C, Research Article
Yaqiong Wang, Yiran Wu, Yuming Yu, Jie Su, Yi Qiu, Liangbing Gan
Benzylamine selectively adds to one of the two carbonyl groups on the 9-membered orifice to form an N,O-aminal moiety. Subsequent oxidation and hydrogen atom transfer lead to a decarboxylation process and formation of a nor [59]fullerene derivative.
