Development of 19F‐detected 1,1‐ADEQUATE for the characterization of polyfluorinated and perfluorinated compounds


Polyfluorinated and perfluorinated compounds in the environment are a growing health concern. 19F‐detected variants of commonly employed heteronuclear shift correlation experiments such as heteronuclear single quantum correlation (HSQC) and heteronuclear multiple bond correlation (HMBC) are available; 19F‐detected experiments that employ carbon–carbon homonuclear coupling, in contrast, have never been reported. Herein, we report the measurement of the 1JCC and nJCC coupling constants of a simple perfluorinated phthalonitrile and the first demonstration of a 19F‐detected 1,1‐ADEQUATE experiment.
