organometallic compounds such as allyl-zinc, -magnesium, -lithium and saturated lithium compounds are shown to readily undergo addition reactions with conjugated enynes: HCCC(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

1-N,N-Dialkylamino-1-buten-3-ynes, HC = CCH = CHNR2 (R = CH3 or C2H5, E/Z ratio approximately 97:3) have been prepared in 80 and 84% yields by treating the Mannich-coupling products from HC = CCH2OCH3 and R2NCH2OH, CH3OCH2C = CCH2NR2, with two equivalents of potassium amide in liquid ammonia and subsequently adding methanol or ammonium chloride.
