Metal Chelates Based on Isoxazoline[60]fullerenes

Fullerene C60 reacts with a variety of nitrile oxides, providing access to an array of fullerene-fused heterocycles bearing covalently linked chelate moieties. The improved chelating property of the newly synthesized isoxazoline[60]fullerene adducts toward transition metals allows the syntheses of octahedral and square-planar organometallic compounds of rhenium, iridium, and platinum. This new approach has great potential as a general route to other novel derivatives containing catalytically active transition metals.
