Novel Synthesis and Crystal Structure of 1,4-Bis(3-chloro-1,1,3-trimethylbutyl)benzene

Abstract A symmetrical isobutene adduct was synthesized with high yield at −80 °C by means of the 1,4-bis(1-chloro-1-methylethyl)benzene/isobutene system using tetrabutylammonium chloride. The main product under the reaction conditions applied was the symmetrical isobutene adduct, which was crystallized from a hexane/dichloromethane solution and the crystals were analyzed by X-ray crystallography.
