Procedure

5-(2,6,6-trimethyl-3-oxo-cyclohex-1-enyl)-3-methyl-1-phenylsulphonyl-penta-2,4-diene was prepared by oxidation of 5-(2,6,6-trimethyl-cyclohex-1-enyl)-3-methyl-1-phenyl-sulphonyl-penta-2,4-diene by means of sodium meta-periodate in accordance with the process described in French Pat. No. 2,071,508. The product oxidised in this way was itself obtained by reacting sodium phenylsulphinate with 5-(2,6,6-trimethyl-cyclohex-1-enyl)-3-methyl-1-chloro-penta-2,4-diene as described in Example 1.
