Preparation of cyclic ketone |
| abstract |
The invention provides a process for the preparation of cyclic ketones of the general formula <CHEM> in which R represents an optionally substituted alkyl or cycloalkyl group and R<1> and R<2> independently represent an optionally substituted alkyl, cycloalkyl or aryl group, which comprises heating a compound of the general formula <CHEM> in which X represents a chlorine or bromine atom and R is as defined above, with a compound of the general formula <CHEM> in which R<1> and R<2> are as defined above, in the presence of an organic acid. Certain cyclic ketones of formula (I) are useful as intermediates in the preparation of certain fungicidally active cyclopentane derivatives. |
