Featuring a reactive functional group, alkynes participate in many organic reactions. Such use was pioneered by Ralph Raphael, who in 1955 wrote the first book describing their versatility as intermediates in synthesis. Being more unsaturated than alkenes, alkynes characteristically undergo reactions that show that they are "doubly unsaturated". Alkynes are capable o…
WebQu15: Working forwards : simple hydration of internal alkynes gives a 50:50 mixture of ketones, whilehydroboration / oxidation of an alkyne can be more selective at giving the C=O on the less hindered side, especially if one uses 9-BBN over BH 3 (9-BBN is more hindered and therefore the steric effect is enhanced 96% > 75%).
