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）反应生成[Rh(F)(PEt₃)₃] (2)和官能化烯烃Z-CF₃CH═CH(E)（E = GePh₃ (4a)，Si(OEt)₃ (7)）。使用密度泛函理论计算评估了可能的反应途径。[Rh(E)(PEt₃)₃]与HFO-1234ze（E-1,3,3,3-四氟丙烯）反应通过两种不同的反应途径生成铑氟化物配合物2和[Rh{(E)-CH═CH(CF₃)}(PEt₃)₃] (9)。使用配合物1和5作为催化剂获得了官能化结构单元。
