Two novel thermal rearrangements providing 2,3-disubstituted 1,3-butadienes are described: the isomerization of 1,9-decadien-5-yne (3) to 4,5-bismethylene-1,7-octadiene (5) and of 1-acetoxy-6-hepten-2-yne (10) to 2-acetoxy-3-allyl-1,3-butadiene (12).
描述了提供2,3-二取代的1,3-丁二烯的两个新颖的热重排:1,9-癸二烯-5-炔(3)异构化为4,5-双亚甲基-1,7-辛二烯(5)和1-乙酰氧基-6-庚-2-炔(10)变成2-乙酰氧基-3-烯丙基-1,3-丁二烯(12)。
