Fluorochemicals from fluorspar via a phosphate-enabled
The sequential milling of acid-grade fluorspar (1 equiv) with three portions of K 2 HPO 4 (overall 2.5 equiv) at 35 Hz gave a fluorinating reagent (Fluoromix) of improved reactivity in the presence of H 2 O (2 equiv), affording 1 isolated in 86% yield using one instead of four equivalents of CaF 2 (figs. S1 to S4).
