N‐Alkylation of Fulleropyrrolidines by Aminomethylation Reaction of Ketones/Arylboronic Acids.

Abstract: N‐alkylation of fulleropyrrolidines in the presence of polyformaldehyde and p‐toluenesulfonic acid was systematically investigated. With the addition of ketones/arylboronic acids, a series of novel N‐alkyl fulleropyrrolidines were formed. Nevertheless, in the absence of ketones/arylboronic acids, scarce N‐methyl fulleropyrrolidines were obtained with the aid of benzyl alcohol. Possible reaction pathways for the formation of N‐alkyl fulleropyrrolidines were proposed to elucidate the above reaction process. [ABSTRACT FROM AUTHOR]
