cf. CA 61, 8291e. The reactions of a series of 2-halobenzothiazoles and the corresponding 6-nitro derivatives with MeO- and PhS- were studied in MeOH at 25°. 2-Fluorobenzothiazole reacts with MeO- about 20 times faster than with PhS-. With the other 2-halo derivatives, the reactivity with MeO- and PhS- is comparable. Only in the 6-nitro derivatives was the normal Ph- >>MeO- reactivity found. In both series with MeO- the order of reactivity was F>>Cl>Br>I and this was correlated with the 6 para values for the halogens. A linear relationship was found between the polarizability of the leaving group (as measured by the log of the C-halogen bond refractivity constant) and the log of kPhS-/ k MeO-.
