Erbing, Elis; Sanz-Marco, Amparo; Vazquez-Romero, Ana; Malmberg, Jesper; Johansson, Magnus J.; Gomez-Bengoa, Enrique; Martin-Matute, Belen published an article on February 2 ,2018. The article was titled 《Base- and Additive-Free Ir-Catalyzed ortho-Iodination of Benzoic Acids: Scope and Mechanistic Investigations》, and you may find the article in ACS Catalysis.Application In Synthesis of 7-Iodoisobenzofuran-1(3H)-one The information in the text is summarized as follows:

A protocol for the C-H activation/iodination of benzoic acids catalyzed by a simple iridium complex has been developed. The method described in this paper allows the ortho-selective iodination of a variety of benzoic acids under extraordinarily mild conditions in the absence of any additive or base in 1,1,1,3,3,3-hexafluoroisopropanol as the solvent. The iridium catalyst used tolerates air and moisture, and selectively gives ortho-iodobenzoic acids with high conversions. Mechanistic investigations revealed that an Ir(III)/Ir(V) catalytic cycle operates, and that the unique properties of HFIP enables the C-H iodination using the carboxylic moiety as a directing group.

Quality Control of 7-Iodoisobenzofuran-1(3H)-oneOn September 30, 1988 ,《The internal steric push-effect: its consequences on the reactivity of carbonyl functions in 3-substituted phthalic anhydrides》 was published in Spectroscopy Letters. The article was written by Kayser, Margaret M.. The article contains the following contents:

The 13C NMR for a number of 3-substituted phthalic anhydrides and corresponding lactones were measured. Substituent effects were discussed. MM2 calculations for several 3-substituted phthalic anhydrides predict that the substituent and the neighboring carbonyl group remain coplanar and within the plane of the aromatic ring. To alleviate the imposed crowding, there is an in-plane distortion of the bond angle of the substituent and the carbonyl function. The observed angle of distortion increases with increasing steric demand of the substituent, in agreement with repulsive van der Waals interaction between those two groups. Diminished reactivity of the ortho carbonyl groups vis-a-vis nucleophiles in 3-substituted phthalic anhydrides may be linked to the internal steric push-effect which causes the displacement of electrons in the CO bond from O to C.

The title of the article was 《Oxygen-17 nuclear magnetic resonance spectroscopic study of substituted phthalic anhydrides and phthalides》.Computed Properties of C8H5IO2 The author mentioned the following in the article:

17O chem. shift data (natural abundance) for 3-substituted phthalic anhydrides and 4- and 7-substituted phthalides in acetonitrile at 75° are reported. Steric interactions of substituents ortho to the carbonyl groups result in deshielding effects (9-22 ppm) relative to parent compounds regardless of the electronic character of the substituents. Factors contributing to the deshielding effects are discussed. The relationship between 17O chem. shifts and regiochem. of the phthalic anhydrides is discussed.
