The reaction of the rhodium(i) complexes [Rh(E)(PEt3)3] (E = GePh3 (1), Si(OEt)3 (5)) with HFO-1234yf (2,3,3,3-tetrafluoropropene) afforded [Rh(F)(PEt3)3] (2) and the functionalized olefins Z-CF3CH[double bond, length as m-dash]CH(E) (E = GePh3 (4a), Si(OEt)3 (7)). Conceivable reaction pathways were assessed using DFT calculations. Reactions of [Rh(E)(PEt3)3] with HFO-1234ze (E-1,3,3,3-tetrafluoropropene) yielded the rhodium fluorido complex 2 and [Rh{(E)-CH[double bond, length as m-dash]CH(CF3)}(PEt3)3] (9) via two different reaction pathways. Using complexes 1 and 5 as catalysts, functionalized building blocks were obtained.

铑（i）配合物[Rh（E）（PEt3）3]（E = GePh3（1），Si（OEt）3（5））与HFO-1234yf（2,3,3,3-四氟丙烯）的反应）得到[Rh（F）（PEt3）3]（2）和官能化的烯烃Z-CF3CH [双键，长度为m-虚线CH（E）（E = GePh3（4a），Si（OEt）3（ 7））。使用DFT计算评估可能的反应途径。[Rh（E）（PEt3）3]与HFO-1234ze（E-1,3,3,3-四氟丙烯）的反应生成了氟化铑络合物2和[Rh {（E）-CH [双键，长度为m-dash] CH（CF3）}（PEt3）3]（9）通过两个不同的反应途径。使用配合物1和5作为催化剂，获得了功能化的结构单元。
