Process for the preparation of geminal diarylalkanes, new geminal diarylalkanes and alk(en)ylated aromatic compounds

摘要

The invention relates to a new process for the preparation of geminal diarylalkanes of the formula ##STR1## by Friedel-Crafts alkylation of aromatic compounds with specific aliphatic halogen compounds (addition compounds of CCl.sub.4 , to -olefins), to new geminal diarylalkanes and the aralkyl compounds resulting as intermediates.
