The Prato reaction is a particular example of the well-known 1,3-dipolar cycloaddition of azomethine ylides to olefins. In fullerene chemistry this reaction refers to the functionalization of fullerenes and nanotubes. The amino acid sarcosine reacts with paraformaldehyde when heated at reflux in toluene to an ylide … See more In one application a liquid fullerene is obtained when the pyrrolidone substituent is a 2,4,6-tris(alkyloxy)phenyl group although a small amount of solvent is still possibly present. See more This reaction was derived from the work of Otohiko Tsuge on Azomethine Ylide Chemistry developed in the late 1980s. Tsuge's work was applied to fullerenes by Maurizio Prato, thus gaining the name. See more Just as in other fullerene reactions like the Bingel reaction or Diels-Alder reactions this reaction can be reversed. A thermal cycloelimination of a pyrrolidinofullerene with a strong See more It is known that the Prato reaction is very useful to functionalize endohedral metallofullerenes. Prato reaction on M3N@C80 gives initially [5,6]-adduct (kinetic product), which convert upon heating to the [6,6]-adduct (thermodynamic … See more • Elizabeth Wilson (4 February 2002).
