In the Alkylation of Cyclohexanone,better Yields Are Obtained by First

Essay

In the alkylation of cyclohexanone,better yields are obtained by first reacting cyclohexanone with an equivalent of lithium diisopropylamide in THF and then adding the alkyl halide,rather than mixing cyclohexanone,alkyl halide,and a catalytic amount of sodium ethoxide in ethanol.Explain this observation by pointing out what the problems with the second reaction conditions might be and how the first set of reaction conditions help alleviate the problems.
