IT WAS shown by Gombergl that the monohalogen derivatives of triphenylcarbinol chloride can be prepared from benzophenone dichloride and the corresponding phenyl halide by the Friedel and Crafts reaction. The position of the halogen was assumed to be the para. This was proven in the case of the monochlor compound by preparing it from the dichloride of p- chlorbenzophenone and benzene. We now undertook to condense in a similar way the ...
