Abstract
The effect of acetone on the rate of hydrogen-atom transfer in the sys tem nitroxyl radical-spatially hindered hydroxylamine-hexane (neutral solvent) was studied at room temperature. An increase in the acetone c oncentration from 0 to 100% causes a decrease in the reaction rate. Th e main factor responsible for the decrease in the rate of the hydrogen -atom transfer in the presence of acetone is a decrease in the concent ration of free hydroxylamine which is due to the formation of unreacti ve H-complexes of hydroxylamine with acetone.
