Is there any bona fide example of O–H⋯F–C bond in solution? The cases of HOC(CF3)2(4-X-2,6-C6H2(CF3)2) (X = Si(i-Pr)3, CF3)

Abstract
The reinvestigation of the title compounds, which are the only examples reported to show experimentally (by NMR) O–HF–C bonds in solution proves that the NMR data were misinterpreted and the restrictions to rotation of one CF3 group are due to crowding, not to intramolecular O–HF–C bond.
