Kinetics of Alkylated Biladiene-a ,c Deprotonation

摘要

The kinetics of deprotonation of l,3,7,13,17,19-hexamethyl-2,8,12,18-tetrabutylbiladiene-a,c dyhydrobromide on treatment with nucleophilic reagents(pyridine,dimethylformamide,dimethyl sulfoxide)in carbon tetrachloride was measured by electron absorption spectroscopy in the temperature range of 293.15-303.15 K.The effects of the reactant concentrations,the temperature,and the electron-donor properties of the nucleophilic reagent on the kinetics of deprotonation of biladiene-a,c as the salt with HBr are discussed.
