Monoprotected l-Amino Acid (l-MPAA), Accelerated Bromination, Chlorination, and Iodination of C(sp2)?H Bonds by Iridium(III) Catalysis
Halogenated arenes are important structural motifs commonly found in biologically active molecules and used for a variety of transformations in organic synthesis. Herein, we report the mono-protected l-amino acid (l-MPAA) accelerated iridium(III)-catalyzed halogenation of (hetero)anilides at room temperature. This reaction constitutes the first example of an iridium(III)/l-MPAA-catalyzed general halogenation of (hetero)arenes through C(sp2)?H activation. Furthermore, we demonstrate the potential utility of our method through its use in the synthesis of a quinolone derivative.

A palladium-catalyzed regiospecific synthesis of N-aryl benzimidazoles
(Chemical Equation Presented) Highly tolerated: A catalytic method employing [Pd2(dba)3] and XPhos or RuPhos permits the efficient synthesis of N-aryl benzimidazoles in regioisomerically pure form starting from ortho-halo-anilides (see scheme), and tolerates a wide range of functional groups, dba = trans,trans-dibenzylideneacetone.
