The preceding paper describes the reanalysis by Kerr and Parsonage (following discussions with one of us, H.W.S.) of some of our published work. We are grateful to Dr. Kerr for communicating their conclusions to us. We agree in principle with their analysis, and the present communication is to repor

โฆ Synopsis
The recent paper of Choo and Benson [l] prompted us to communicate our most recent results for the gas-phase decomposition of the t-butoxy radical. The method we have used was to decompose ditertiary butyl peroxide (-10-5M) in the presence of nitric oxide (-10-5M) and inert gas (25-1500 torr) in a static system over the temperature range of 130-170ยฐC. The following scheme gives the important steps in this system:

Hexafluoro-t -butoxy radicals have been generated by reacting fluorine with hexafluoro-2-methyl isopropanol: Over the temperature range of 406-600 K the hexafluoro-t-butoxy radical decomposes exclusively by loss of a CF3 radical [reaction (-2)] rather than by loss of a CH3 radical [reaction (-111:
By allowing the t-butoxy radical to decompose in the presence of nitric oxide, it has been possible to determine rate constants for decomposition by the measurements of the relative rates (2) and (3): The value of k3(x) has been determined in the presence of several inert gases (CF,, SF,, N,, and A
The reaction of CF, radicals with NH, has been studied over a wide temperature range 298-673 K, using the photolysis and the thermal decomposition of CF,I as the free radical source. It was found that the reaction could not be explained in terms of a simple mechanism CZFG in the whole temperature
s-Butoxy radicals have been generated by reacting fluorine with s-butanol: Over the temperature range 398.6 to 493.3 K the s-butoxy radical decomposes by two different pathways to yield acetaldehyde and propionaldehyde, acetaldehyde being the major product: (1) The ratio k , / k z was found to be
