Abstract


For the first time, a selective and efficient method for the synthesis of 1',4'-dialkyl-1',4',5',6'-tetrahydropyrazino[2',3':1,9](С60-Ih)[5,6]-fullerenes (alkyl = methyl, ethyl, isopropyl) was developed based on the reaction of C60 fullerene with N-substituted ethylenediamines in PhMe–DMF medium effected by ultrasound.

 


Keywords


fullerene piperazine adducts; secondary acyclic diamines; [4+2] cycloaddition reactions of C60 fullerene; selective sonochemical reactions; ultrasound.
