Versuchsvorschrift

The 4-isopropoxy-2,3,6-trimethyl-benzyl-triphenylphosphonium chloride employed as the starting material is prepared by the procedure described in Example 18 by alkylation of 2,3,5-trimethylphenol to give 2,3,5-trimethylphenyl isopropyl ether (boiling point 115° C/11 mmHg), by haloformylation of the ether obtained to give 4-isopropoxy-2,3,6-trimethyl-benzyl chloride (nD20 = 1.5433) and by reaction of the latter compound with triphenylphosphine.
