A method for producing 2-alkyl-2-cycloalkene-1-one that can be obtained in high yield and high purity, and alkyl (3-oxo-2-) useful as a perfume material using the same A process for producing alkylcycloalkyl) acetates is provided. [1] 2- (1-hydroxyalkyl) -cycloalkane-1-one is subjected to dehydration isomerization in the presence of an acid and a platinum group metal catalyst and represented by the following general formula (2). A method for producing alkyl-2-cycloalkene-1-one, and [2] a method for producing alkyl (3-oxo-2-alkylcycloalkyl) acetate, which is useful as a perfume material, using the same. (In the formula, n is 1 or 2, R 1 and R 2 each represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, or a ring is formed through a carbon atom adjacent to R 1 and R 2. It may be formed.) [Selection figure] None |
