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)胚芽和甲硅烷基络合物活化四氟丙烯。

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。
