The reaction of dicobalt hexacarbonyl complexes of acetylene and its phenyl and dimethyl derivatives with the methyl ester of 1-methyl-2-(trimethylsilyl)-1-cyclopropene-3-carboxylic acid with adsorption on a silica gel or NaX zeolite surface leads to the formation of a mixture of bicyclohex-2-en-4-one and tricyclo2,4>heptan-5-one derivatives, whereby the yields and the composition of products are dependent on the type of the adsorbent.It has been found that under the reaction conditions partial isomerization of the bicyclohex-2-en-4-one derivativ es into substituted phenols occurs.Action of anhydrous KF and crown-ether in acetonitrile on the bicyclohex-2-en-4-one derivatives in acetonitrile leads to protodesilylation.
