✦ Synopsis

Dehalogenation of the polyhalides, CHCl 3 , C 60 (CCl 2 ), CH 2 I 2 , and 7,7-dibromobicyclo(4,1,0)heptane, by treatment with zinc, magnesium or NaOH powder, followed by the in situ reaction with fullerene in the presence of ultrasonic irradiation and in the ionic liquid solvents, [bmim][PF 4 ] or [omim][BF 4 ], provided [6,6]-junction cycloaddition products in 53-79% yields. Only single isomers of the products were detected in the reaction solutions.
