Abstract

1, 3-Cycloalkadiones were prepared by the reaction of l, 2-bis (trimethylsiloxy) cycloalkenes with chloromethyl methyl ether followed by treatment of the resulting 2-hydroxy-2- methoxymethyl cycloalkanones with potassium hydrogen sulfate. The first step of the reactions was effectively catalyzed by active zinc reagents prepared from zinc–copper and alkyl iodides.
