Fig. 3. Scope for ¹¹C-2,2,2-trifluoroethoxylation of arenes.

LG = leaving group. Yields are based on HPLC analyses of reaction mixtures. All yields are based on [¹¹C]fluoroform conversion into the products, decay-corrected and expressed as mean ± SD (n = 3). Radioactive products were collected at least once for each substrate to check that HPLC yields matched isolated yields. A Substrate scope for heteroarenes using reaction condition (A). B Substrate scope for homoarenes using reaction condition (B). Auxiliary derived from Meldrum’s acid.
