Abstract
Abstract Reactive organometallic compounds such as allyl-zinc,-magnesium,-lithium and saturated lithium compounds are shown to readily undergo addition reactions with conjugated enynes: HC C C (R) C (R)(R), but the reactivity is reduced when the steric hindrance around the double bond is increased. With each organometallic compound used, this reaction is regioselective: 3, 4 addition with organozinc compounds, 1, 2 addition with ...
