Electron-deficient molecule C-60 readily undergoes reactions with mines because of their nucleophylic properties. Some monomers and polymers of nitrogen C-60 derivatives have been synthetised. Easy addition of amines is used in synthesis of monomers, as well as polymers of C-60, both in mono-layers and 3D structures. However, their instability does not permit detailed structural studies. In this paper theoretical study of direction of addition to C-60 was done using computational modelling, and the procedure for synthesis of phenyl-hydrazine derivative with free amino group is described. Amino derivatives obtained in these reactions can be important new materials with multiple potential application in medicine, biology and engeneering.
