摘要:
A fluorine derivative of 3,3-dimethyl-butan-2-one, of the formula ##STR1## in which X is hydrogen or fluorine,is produced by reacting a metal fluoride in a diluent and at elevated temperature with a sulphonic acid ester of the formula ##STR2## in which R is optionally substituted alkyl or optionally substituted aryl, andY is hydrogen or O--SO.sub.2 --R.The product is useful in the synthesis of fungicides.
