Amine-Assisted C−Cl Bond Activation of Aryl Chlorides by a (Phebox)Rh-Chloro Complex

Abstract

Oxidative addition of chlorobenzene and p -chlorotoluene by (Phebox)RhCl 2 (H 2 O) ( 1 ) in the presence of diisopropylamine was examined and was shown to produce the corresponding aryl complexes (Phebox)RhCl(Ar)(H 2 O) in high yields via C−Cl bond cleavage. Reaction of 1 with chloropyridine in the presence of diisopropylamine provided a pyridinium rhodate complex.
