The diastereomeric product ratios from reactions involving the addition of various reagents to the carbonyl of φCH3HC-COR compounds varies over a wide range. This variation is interpreted as due partly to changes in the structure of the diastereomeric transition states with changes in the size of R. For example, when R is smaller than the φCH3HC group the diastereomeric product ratios are close to

fragmentation of sterically hindered homobenzylic zinc alcoholates proceeds readily leading to benzyliczinc reagents free from any Wurtz-coupling product. Reaction of these organometallic intermediates with various aldehydes produces new homobenzylic alcohols in moderate to good yields. A 1,4-addition of these newly prepared benzylicorganometallics to an alkylidenemalonate is also reported.
