One-Pot Synthesis of a Variety of 1,4-Alkadienes and 1,2,4-Alkatrienes from Alkynes, Allyl, or Propargyl Compounds and Electrophiles by a (η2-Propene)Ti(O-i-Pr)2-Mediated Reaction

The intermolecular reaction of alkynes with allyl or propargyl compounds mediated by (η2-propene)Ti(O-i-Pr)2 followed by trapping of the resulting vinyltitanium compounds with an electrophile such as H2O, I2 or an aldehyde furnished a variety of 1,4-alkadienes or 1,2,4-alkatrienes.
(η²-丙烯)Ti(O-i-Pr)2催化的炔烃与烯丙基或炔丙基化合物的分子间反应,随后用亲电试剂如H2O、I2或醛捕捉生成的乙烯基钛化合物,可得到多种1,4-炔二烯或1,2,4-炔三烯。
