A solvent-free method for the addition of amines to dialkylacetylendicarboxylates or alkylpropiolates using a planetary ball mill was developed. Conversion of educts was quantitative within five minutes without use of any catalyst or base. Beside the E-/Z-isomers, no side products were formed. addition - amines - alkynes - enamines - green chemistry
CuCl<sub>2</sub>-Mediated Reaction of [60]Fullerene with Amines in the Presence or Absence of Dimethyl Acetylenedicarboxylate: Preparation of Fulleropyrroline or Aziridinofullerene Derivatives
The CuCl2-mediated three-component reaction of C60 with amines and dimethyl acetylenedicarboxylate afforded the fulleropyrrolines in moderate yields. Furthermore, the CuCl2-mediated oxidative [2 + 1] reaction of C60 with aromatic amines bearing a strong electron-withdrawing group provided the aziridinofullerenes and the selective cis-1-bisaziridinofullerenes.
