The transmission of polar effects. Part IX. The ionization and esterification with diazodiphenylmethane of 9-substituted 10-triptoic acids

Canadian Journal of Chemistry, 1969
A series of 9-substituted 10-triptoic acids have been prepared. Their pKa values in 80% 2-methoxy-ethanol–water and 50% ethanol–water at 25° and rate coefficients for esterification with diazodiphenyl-methane in five alcohols at 30° have been measured. The results have been analyzed by linear free energy relations.

New evidence for the mechanism of the tin(II) chloride catalyzed reactions of vicinal diols with diazodiphenylmethane in 1,2-dimethoxyethane

Carbohydrate Research, 2001
A kinetic study of the tin(II) chloride catalyzed reaction of diazodiphenylmethane with ethylene glycol in dimethoxyethane is reported. The preparation and characterization of ethylene glycol monodiphenylmethyl ether, the main product from this reaction, is also reported as well as the preparation of the two diphenylmethyl monoethers of methyl 4,6-O ...

The influence of the hydroxylic solvents on the reaction rates of diazodiphenylmethane with cycloalkylcarboxylic and cycloalkenylcarboxylic acids

2004
The rate constants for the reaction of diazodiphenylmethane with cyclohexylcarboxylic, cyclopentylcarboxylic, cyclohex-3-enylcarboxylic and cyclopent-3-enylcarboxylic acids have been determined in ten alcohols at 30degreesC using the UV-spectroscopic method.
