Description

The kinetics of detritiation of a range of carbon acids activated by different kinds of groups have been investigated in water-hydroxide, methanol-methoxide, and ethanol-ethoxide solutions. The results show that for those acids that can be characterized as normal in the Eigen sense (chloroform, phenylacetylene, and dimethyl sulfone) the rates are up to 10 times faster in water-hydroxide solutions than in methanol-methoxide, not as expected from the basicities of the respective solutions. However, for the acetophenones it is found that kTOMe- > kTOH- and this is also the case for the cyanocarbon acids. The ratio kTOEt-/kTOMe- varies within much narrower limits and is always greater than unity. It is suggested that the rate ratio kTOH-/kTOMe- may be used as an additional probe for the classification of carbon acids
