In reactions of a substrate with complex bases (CB) prepared from organolithium compounds and heavier alkalimetal alkoxides the reaction rates and relative product yields depend on the structure and concentration of the CB components.For the model reaction of C6 with alkyl bromides, changes in the identity and concentration of the alkoxide reduced reaction half-times by as much as three orders of magnitude and higher yields of the product of Wurtz coupling were obtained.Sodium 3-methyl-pentoxide-3 was found to be considerably more effective than sodium t-butoxide.
