Characterization of organic functional groups in model systems for coaly matter employing /sup 19/F NMR
It was deemed appropriate to establish certain criteria necessary for an ideal NMR reagent for general characterization of a wide range of different complex organic functional groups. New /sup 19/F NMR reagents were examined with the new criteria. It appeared that the derivatives formed using trifluoracetyl chlorides were well-resolved in the /sup 19/F NMR spectra. It appeared that this reagent would be useful as an analytical tool for characterization of functional groups. Fluorinated diazoalkane, trifluorodiazoethane, reacted smoothly with alcohols, phenols, and carboxylic acids at room temperature to -10/sup 0/C in the presence of catalysts to yield fluorinated ethers and esters. 4 figures.
