Rhodium-catalysed reactions of 5-aminopent-1-enes with carbon monoxide and hydrogen give 2-piperidinone derivatives in high yields under mild conditions. Reaction of allylamine under similar conditions gave exclusively 2-pyrrolidone in high yield and reactions of 4-aminobut-1-enes gave mixtures of 2-piperidinones and 2-pyrrolidinones. The role of the hydrogen in these reactions is discussed.
铑在5-氨基戊-1-烯与一氧化碳和氢的催化下,在温和的条件下以高收率得到2-哌啶酮衍生物。烯丙胺在相似条件下的反应仅以高收率得到了2-吡咯烷酮,而4-氨基丁-1-烯的反应则得到了2-哌啶酮和2-吡咯烷酮的混合物。讨论了氢在这些反应中的作用。
