and practical synthesis of 1,1-bis(triflyl)alkenes via self-promoting condensation of Tf2CH2 and aldehydes was developed and chemical behavior of these alkenes was investigated. Among the alkenes, easily isolable 1,1-bis(triflyl)alkadienes derived from α,β-unsaturated aldehydes could be used as useful building blocks for 1,1-bis(triflyl)alkanes. The 1,1-bis(triflyl)alkane thus obtained showed catalyst
通过Tf 2 CH 2和醛的自促进缩合反应,合成了一种方便实用的1,1-双(三氟乙)烯烃,并研究了这些烯烃的化学行为。在烯烃中,衍生自α,β-不饱和醛的易分离的1,1-双(三氟乙)烷二烯可用作1,1-双(三氟乙)烷烃的有用结构单元。如此获得的1,1-双(三氟甲基)烷烃在缩醛形成反应中显示出催化剂活性,该反应是布朗斯台德酸催化的典型反应。
