Ask chemistry experts a few questions: Can the enol anion of ethyl acetoacetate react with diethyl carbonate? What is the product? What is the product of ketone hydrolysis? Can the enol anion of ethyl acetoacetate react with α-bromoketone, α-bromoester and ethylene oxide? What products are there? Can the enol anion of acetone react with diethyl carbonate, α-bromoketone, α-bromoester and ethylene oxide? What products are there? Asymmetric ketone reacted in aprotic solvent under the catalysis of strong base to obtain the kinetic control product (Xing Qiyi, P686). Must the alkali here be a strong alkali (such as sodium hydroxide, LDA, sodium amino)? Like sodium alkoxide, is it a product controlled by thermodynamics?
