The rapid PdII-catalysed rearrangement of 3-acetoxy-1,4-dienes to 1-acetoxy-2,4-dienes [e.g.(2E,5Z)-4-acetoxydeca-2,5-diene →(3E,5Z)-2-acetoxydeca-3,5-diene (ca. 80%)] occurs in stereoselective and regio-selective manner.
Pd II催化的3-乙酰氧基-1,4-二烯快速重排为1-乙酰氧基-2,4-二烯[例如(2 E,5 Z)-4-乙酰氧基癸二-2,5-二烯→(3 E,5 Z)-2-乙酰氧基癸基-3,5-二烯(约80%)]以立体选择和区域选择的方式发生。
