摘要：

The reinvestigation of the title compounds, which are the only examples reported to show experimentally (by NMR) O - H center dot center dot center dot F - 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 - H center dot center dot center dot F - C bond.
