Chemical Reaction Mechanisms

Abstract Modification of the traditional. Gomberg reaction conditions provides a simple, economical. route to 2‐chlorobiphenyl‐1′,2′,3′,4′,5′,6′‐ 14 C 6 (I). The reaction of benzene‐U‐ 14 C 6 with an excess of the diasonium salt from 2 ‐chloroaniline produces 14 C‐labelled I in 10% radiochemical. yield. This method should be applicable to the preparation of any chlorinated biphenyl having one unsubstituted ring .
