A regioselective step-by-step C60Cl6 functionalization approach affords a novel family of C60Ar5Th'Th''H fullerene derivatives with promising antiviral properties.

We report a novel reaction of the recently discovered family of fullerene derivatives C1-C60Ar5Th' with thiophene derivatives Th''H yielding a previously unknown family of C1-C60Ar5Th'Th''H compounds with three different types of functional aromatic addends attached to the carbon cage. The discovered reaction paves a way to the synthesis of novel C60 fullerene derivatives with promising antioxidant and antiviral properties.

Water-Promoted Reaction of C60Ar5Cl Compounds with Thiophenes Delivers a Family of Multifunctional Fullerene Derivatives with Selective Antiviral Properties.

Here we report a reaction of the fullerene derivatives C60Ar5Cl, which enables the substitution of Cl with thiophene residues and the formation of the novel family of C1-symmetrical C60 fullerene derivatives with six functional addends C60Ar5Th. The discovered reaction provided a straightforward approach to the synthesis of previously inaccessible multifunctional water-soluble fullerene derivatives, including the compounds with antiviral activity against human immunodeficiency and influenza viruses.
