Reaction of single crystals of benzoic and trans-cinnamic acids with 200 Torr pressure of ammonia gas in a sealed glass bulb at 20 °C generates the corresponding ammonium salts; there is no sign of any 1:2 adduct as has been reported previously for related systems. Isotopic substitution using ND 3 has been used to aid identification of the products. Adipic acid likewise reacts with NH3 gas to form a product in which ammonium salts are formed at both carboxylic acid groups. Reaction of 0.5 Torr pressure of NO2 gas with single crystals of 9-methylanthracene and 9-anthracenemethanol in a flow system generates nitrated products where the nitro group appears to be attached at the 10-position, i.e. the position trans to the methyl or methoxy substituent on the central ring. Isotopic substitution using 15NO2 has been used to confirm the identity of the bands arising from the coordinated NO2 group. The products formed when single crystals of hydantoin are reacted with NO2 gas under similar conditions depend on the temperature of the reaction. At 20 °C, a nitrated product is formed, but at 65 °C this gives way to a product containing no nitro groups. The findings show the general applicability of infrared microspectroscopy to a study of gas-solid reactions of organic single crystals.

Theoretical data are presented for the determination of second-order rate constants of reaction of electrode-generated intermediates with reactants in limiting concentrations for three common reaction mechanisms.The method is applicable to second-order reactions with rate constants ranging from about 106 M-1s-1 up to the diffusion-controlled limit.In cases where heterogeneous charge transfer kinetics contribute to the response, calculations must be carried out taking into account the heterogeneous rate constant.The kinetic method is demonstrated using the proton transfer reaction between a radical cation and pyridine, with a rate constant of 2.3*108 M-1s-1.The method is potentially applicable to a wide range of reactions of electrode-generated intermediates.
