copper(I) salts react with enones, including esters and aldehydes, to give β-silyl carbonyl compounds in good yield. The β-silylketones can be used in synthesis without risk to the silyl group and the enone group can be restored by bromination-desilylbromination with copper(II) bromide. The principle is illustrated with syntheses of carvone and dihydrojasmone.
