A metathetical reaction between carbon tetrachloride and toluene to give benzyl chloride and chloroform occurs at temperatures above 200Β°C (k = 4.8 X 1Olo e-82,m/RT cc mole-'sec-'). The reaction does not involve free radicals, as is shown by the kinetic behavior of the system, by the lack of effect

β¦ Synopsis
The reaction between diasodiphenylmethane and carboxylic acids in ethanol or other alcohols as solvent has been much studied (see references 2 to 1Y in reference (1) of this note and references 2 to 8) and the main features of the mechanism have now been established (1,2).

## Abstract The rate constants for the reaction of different cycloalkenylcarboxylic, cycloalkenylacetic acids, and phenylacetic acid with diazodiphenylmethane were determined in 12 aprotic solvents at 30Β°C. In order to explain the kinetic results through solvent effects, the secondβorder rate const
Equilibria and kinetics of proton-transfer reactions in toluene between a set of m-and o-substituted (methyl, methoxy, chloro, nitro and hydroxy) benzoic acids and the carbinol base (colourless) of Crystal Violet were studied spectrophotometrically.
