2-Isopropoxy-1-lithio-2-phenyl-1-alkenes are prepared by iodine-lithium exchange reactions of (Z)-1-iodo-2-isopropoxy-2-phenyl-1-alkenes and sec-butyl- or tert-butyllithium. These vinyllithium derivatives react with various electrophiles (methanol, deuterium oxide, iodomethane, phenylselenenyl bromide) to yield substituted enol ethers stereoselectively. The corresponding substituted acetophenones are obtained after acidic hydrolysis.
