METHOD FOR PRODUCING 2-SUBSTITUTED CARBOXYLIC ACIDS

摘要

The invention relates to a method for producing tertiary butyl esters that are substituted in position 2, by the alkylation of the appropriate tertiary butyl ester enolates. In addition, the invention relates to a method for producing corresponding free carboxylic acids by the acidic hydrolysis of the aforementioned tertiary butyl esters and their conversion into additional carboxylic acid esters.
