Hydrolysis rates and products of isopropyl, cyclopentyl and cyclohexyl phenyl ethers were studied in concentrated aqueous perchloric acid solutions.The activation parameters, solvent deuterium isotope effects, dependences of the reaction rates on acid concentration, substituent effects and products were in agreement with the A-1 mechanism.The pKSH+ values (-6.13 to -5.76) and the slope parameters m* (av. 0.98 +/- 0.03) were measured spectrophotometrically by the excess acidity method.They were used to calculate the m++-parameters (1.46-2.01).Comparisons weremade with the hydrolyses of exo- ad endo-2-norbornyl phenyl ethers and secondary alyl methanesulfonates.
Preparation of diphenolics

, (2008/06/13)
A process for the production of diphenolic compounds having a divalent bridge. A first disubstituted phenol is reacted with an aldehyde in the presence of a secondary amine and excess alcohol to form an ether intermediate. The ether intermediate is reacted with a phenol having an open ortho or para position to form a diphenolic.
Basic ethers of cyclohexylphenols with β blocking activity. Synthesis and pharmacological study of exaprolol

The paper discribes the preparation and study of the pharmacological properties of the basic ethers of cyclohexylphenols. The compounds with a single cycloaliphatic radical ortho to the basic chain, and in particular the one with a cyclohexyl (exaprolol), were found to be particularly active in blocking the β adrenergic receptors, as antiarrhythmics and local anesthetics, while the introduction of a second radical or the shift of the cycloaliphatic radical to meta or para position caused the said pharmacological activities to disappear almost entirely, with the exception of the local anesthetic action.
