- W2080668188 abstract "Abstract During our program to synthesize fluorinated aminosugars [1] we needed a quite neutral nucleophilic fluorinating reagent to obtain 3,6 difluoroglucosamine. Et3N,3HF was not nucleophilic enough and other reagents like MF or R4N+F- were too basic and led to elimination products (because of the axial 4-OMs). We found that when adding some Et3N to Et3N,3HF, reaction worked in good yields. Our first results were consistent with the formation of a complex Et3N,2HF which could be isolated as a very hygroscopic white powder. Preparation of Et3N,2HF is described together with some presumption of structure. Comparison of its reactivity with that of other fluorinating reagents will be discussed." @default.
