Complexes of Carboxylic Acids with Pyridines and Pyridine N-Oxides

HETEROCYCLES, 1994
A brief survey is given of dielectric, spectroscopic, thermodynamic, colligative and conductivity properties of non-aqueous solutions of carboxylic acid complexes with pyridines and pyridine N-oxides. Selected problems of solid state are also reviewed.

Action of Thionyl Chloride on Carboxylic Acids in Presence of Pyridine

Nature, 1953
IN order to use thionyl chloride most effectively for the preparation of acyl chloride, RCO.Cl, a knowledge of the sequence of reactions occurring is desirable. Trichloroacetic acid reacts extremely slowly with thionyl chloride even at higher temperatures; but Carre and Libermann1 have shown that pyridine (1 mol.) helps the reaction.
