Rate constans for the decomposition of (Z)-syn ethers derived from some 4- or 5-substituted 2-nitrobenzenediazonium salts have been measured in both basic ethanol.For some compounds the rate of decomposition is independent of the base concetration while for others the rate is first order in base concetration.Solvent and substituent effects poit to the base-independent mechanism occuring on the free diazonium salt formed by ionization of the Z ether while the base-dependent mechanism occurs on the Z ether itself.Mechanisms are proposed for each of these reactions.
