## Abstract The rate of the reaction between ethyl tosylate and chloride as well as bromide ion has been measured in hexamethylphosphoric triamide in the presence of several counterions. Rate constants for the free ions at 25.0° are 14.4 mole^−1^ for chloride and 2.0 mole^−1^min^−1^ for bromide, bo
## Abstract Rate data are reported for the reactions of 2‐chloro‐5‐nitropyridine **2a**, 2‐chloro‐3‐nitropyridine **2b**, and the corresponding 2‐phenoxy derivatives **2c** with __n__‐butylamine, pyrrolidine and piperidine and **2d** with __n__‐butylamine and pyrrolidine in dimethyl sulfoxide (DMSO
line 14: 1-phenoxy should read 2-phenoxy. Page 129, paragraph 3, line 10: the slope of the plot should read the slopes of the plots. Page 134, paragraph 2, lines 2-4: The reaction of pyrrolidine with 2c in acetonitrile is not base-catalyzed whereas that in DMSO is catalyzed should read The reaction
The use of chemical probes for the characterization of chemical properties was explored for completely non-aqueous aprotic binary solvent mixtures. The Dimroth-Reichardt E T (30) betaine dye, 4-nitrophenol, 4nitroanisole, 4-nitroaniline and N,N-diethyl-4-nitroaniline were used to study preferential
## Abstract Kinetic studies are reported for the reactions with aniline in benzene of a series of X‐phenyl 2,4,6‐trinitrophenyl ethers [X = H; 2‐, 3‐, 4‐CH~3~; 2,4‐, or 2,6‐(CH~3~)~2~] a–f, and the results compared with those of the corresponding nitro derivatives. In the methyl series, kinetic dat
