A structural study of 3- and 4-iodosylbenzoic acids, 3- and 4-iodylbenzoic acids, and their sodium salts
Abstract
The 13C NMR, IR, and UV spectra of 3- and 4-iodobenzoic, 3- and 4-iodosylbenzoic, and 3- and 4-iodylbenzoic acids and their sodium salts have been measured and compared with those of the corresponding 2-isomers. Kinetic data for the catalytic microemulsion hydrolysis of 4-nitrophenyl diphenyl phosphonate in the presence of the iodosyl and iodyl compounds have been obtained. Catalytic efficiency of the 3- and 4-substituted isomers are measured to be three to six orders of magnitude less effective than the corresponding 2-substituted isomers. Possible structural configurations are suggested and discussed.
