Preparation of diphenylmethanes |
摘要 |
Diphenylmethanes such as o-benzyltoluene are prepared by contacting a benzyl halide with a benzene in the presence of a catalytic amount of a normally solid, insoluble perfluorosulfonic acid polymer under reaction conditions. The o-benzyltoluenes are useful intermediates in the production of anthraquinone and anthracene.
