Procedure

The addition of hydrogen chloride to isoprene leads to dichloroisopentane, which adds to vinylidene chloride and undergoes an elimination reaction with bases to give 1,1-dichloro-3,3-dimethyl-1,4-pentadiene. Reaction with sodium phenolate and hydrolysis yields the chloromethyl ketone of the formula (III): ##STR10##
