as both benzoxylate source and oxidant has been developed. The catalytic system was greatly promoted by a pyridine ligand. Good functional groups tolerance was showed in both hypervalentiodine reagents and arene substrates, which can be used for synthesis of aryl benzoates through simple aromatic compounds.

This paper describes the synthesis of a series of Pd(IV) complexes of general structure (N~C)(2)Pd(IV)(O(2)CR)(2) (N~C = a rigid cyclometalated ligand; O(2)CR = carboxylate) by reaction of (N~C)(2)Pd(II) with PhI(O(2)CR)(2). The majority of these complexes undergo clean C-O bond-forming reductive elimination, and the mechanism of this process has been investigated. A variety of experiments, including

This communication describes the synthesis of a family of unusually stable palladium(IV) complexes containing two chelating 2-phenylpyridine ligands and two benzoates. These complexes undergo clean C-O bond-forming reductiveelimination upon heating, and the mechanism of this catalytically relevant process has been studied in detail. Solvent effects, crossover experiments, Eyring plots (which show
formula R4N[I(O2CAr)2] is reported. These compounds are air‐ and moisture‐stable iodine(I) reagents, which were characterized including X‐ray analysis. They represent conceptually new iodine(I) reagents with anions as stabilizers. These compounds display the expected performance as electrophilic reagents upon interaction with electron‐rich substrates. The performance of these compounds in a total of
