Researchers synthesized novel fullerene derivatives, C60 and C70 bis-adducts, using bismalonate linkers. The tether length influenced the symmetry and patterns of fullerene functionalization, offering new insights into fullerene chemistry.
Area of Science:
- Organic Chemistry
- Materials Science
- Supramolecular Chemistry
Background:
- Fullerenes (C60 and C70) are unique carbon allotropes with diverse applications.
- Controlled functionalization of fullerenes is crucial for tailoring their properties.
- Bis-adduct formation offers a pathway to complex fullerene architectures.
Purpose of the Study:
- To synthesize and characterize novel regio- and stereoselective bis-adducts of C60 and C70.
- To investigate the influence of tether length in bismalonate moieties on fullerene addition patterns.
- To explore the formation of a new C70-dumbbell derivative.
Main Methods:
- Synthesis of C60 and C70 bis-adducts using two distinct bismalonate tethered moieties.
- Spectroscopic analysis (e.g., NMR, Mass Spectrometry) to confirm structures and regio/stereoselectivity.
- Characterization of a new C70-dumbbell derivative.
Main Results:
- Four easily isolable regio- and stereoselective bis-adducts of C60 and C70 were successfully synthesized.
- Longer tethered moieties resulted in highly symmetric addition patterns.
- Shorter tethered moieties led to unique and interesting addition patterns on both C60 and C70.
Conclusions:
- Bismalonate tether length is a critical factor in controlling the regioselectivity and stereoselectivity of fullerene bis-functionalization.
- The study demonstrates a versatile method for creating complex fullerene derivatives with tunable properties.
- The findings contribute to the fundamental understanding of fullerene reactivity and the design of novel fullerene-based materials.

Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn...
