Summary: Rappoport9Apeloig, Greenblatt f Solvolysis of 9-(c~-Bromoarylidene)anthrones 3837
aqueous EtOH" is misleading since "TFE-EtOH" should be reserved for
reactions in binary mixturesof the two alcohols.
(34) The method of Raber, Harris. and c~workers"utilizesa statisticalanalysis
of the slope, the intercept,and their uncertainties.Hence, it appears su-
perior in certain cases to the more convenient "two-points'' method.
However,there is an arbitrary criterion which accompanies the statistical
analysis. In our opinion, a parallel arbitrary criterion together with a
quantitativeuse of the log (&E~W/~FE) values of -5 and 1.8 will makethe
two treatments equivalent.
