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.
