β¦ Synopsis
The title reaction is achieved by direct treatment of C60 with malonates in the presence of CBr4 and DBU in good yields. By this significantly improved procedure monoadducts including chiral and sterically demanding dendritic side chains and also hexaadducts can be prepared. -(CAMPS, X.; HIRSCH,
