Addition of carbene to the equator of C(70) to produce the most stable C(71)H(2) isomer: 2 aH-2(12)a-homo(C(70)-D(5h(6)))[5,6]fullerene.

C70 is the second most commercially viable fullerene. Varying surface curvature gives kinetically-controlled chemistry involving unstable bonds near the poles. We synthesised the first derivative at the most thermodynamically stable (equatorial) bonds, which opens up new chemical horizons for C70. Equatorial addition yields thermodynamically stable anchors at which synthetic chemistry may create a multitude of novel highly stable C70-based compounds. Furthermore, chemistry to the rest of the fullerene (e.g. using hydrolytic groups) may be performed kinetically without affecting the stable anchor, make the abovementioned anchor-based compounds water soluble (for example), with potential medical science applications, amongst others.
