Steps:
General procedure for borenium-catalysed hydrodealkylation of alkylarenes
Inside a nitrogen-filled glovebox, 1a and alkylarene were dissolved inC6H5Br (0.5 ml) and transferred into the well of an autoclave. After the head of the autoclave was assembled, the autoclave was taken out ofthe glovebox and connected to a dihydrogen gas cylinder. The connectionline was flushed with dihydrogen three times. Then the autoclave was pressurized to 20 bar of dihydrogen and allowed to stand at room temperature for 24 h. The autoclave was then cooled to -40 °C in a cold ethanol bath for 15 min, followed by releasing the dihydrogen pressure. After removing the head of autoclave, octane and diphenylmethane were added into the well of an autoclave as internal standards. The resulting reaction mixture was then subjected to GC-MS analysis.The identities of products were confirmed by comparison of the mass spectra and retention times of the products with those of authentic compounds.
