Abstract
A study on the acid-induced ring-expansion reaction of the first oxaphosphirane complexes bearing an electron-withdrawing C-substituent is described. The stereoselectively obtained 1,3,4-dioxaphospholane complexes 4a–c, representing the first examples of such fluorinated ligands, were unambiguously characterized by multinuclear NMR, elemental analysis, mass spectrometry, and single-crystal X-ray diffraction studies.
