  Synthetic and thermochemical studies of fluorinated tertiary phosphine ligands R2PRf [R=Cy, Ph, iPr; Rf=CH2CH2(CF2)5CF3] in an organoiron system

  摘要：

  The fluorinated phosphine ligands [PR2Rf (R = Cy (2); Pr-i, (3); Ph, (4); R-f = CH2CH2(CF2)(5)CF3] react with Fe(CO)(3)(BDA) (1) (BDA = (C6H5)CH = CHC(O)CH3, benzylideneacetone) to yield the corresponding Fe(CO)(3)(PR2Rf)(2) = (R = Cy, (5) Pr-i, (6) Ph, (7)) complexes. Infrared studies on the carbonyl complexes and solution calorimetry studies of the reaction of 1 with 2, 3 and 4 have been performed to quantify the donor strength of this series of ligands.

  The fluoroalkylphosphine compounds PR2Rf (R = Cy (1); Pr-i (2); R-f = CH2CH2(CF2)(5)CF3) have been prepared from the reactions of the Grignard reagent IMgRf and appropriate ClPR2 (R = Cy, Pr-i). The fluorinated phosphine ligands [PR2Rf (R = Cy (1); Pr-i (2); Ph (3); R-f = CH2CH2(CF2)(5)CF3] react with [Rh(CO)(2)Cl](2) to yield the corresponding [Rh(CO)Cl(PR2Rf)(2)] (R = Cy (4); Pr-i (5); Ph (6)) complexes. Infrared studies on the carbonyl complexes and solution calorimetry studies of the reaction of (Rh(CO)(2)Cl](2) with PR2Rf (R = Ph, Pr-i, Cy) have been used to quantify the relative ligand donor strength for the series: PCy2Rf approximate to (PPr2Rf)-Pr-i > PPh2Rf. The solid-state crystal structure of [Rh(CO)Cl(PPh2Rf)(2)] (6) is reported. Additionally, these partially fluorinated phosphine ligands (1 and 3) can be used as supporting ligation in rhodium-mediated hydrogenation reactions.
