SONOCHEMICAL SYNTHESIS OF 1',4'-DIALKYL-1',4',5',6'-TETRAHYDROPYRAZINO[2',3':1,9](C60-Ih)[5,6]FULLERENES

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-I_h)[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.
