Silver-mediated fluorination of potassium aryltrifluoroborates with Selectfluor®
摘要:
A simple and practical procedure for the silver-mediated fluorination of aryl- and heteroaryltrifluoroborates with electrophilic fluorine from Selectfluor (R) and LiOH center dot H2O is presented. The reaction procedure is simple and easy to set up, the process produces fluorinated arenes and heteroarenes in good to excellent yields and a wide range of electronically and structurally diverse substrates are tolerated.

synthesis of fluorinated arenes by the iron-mediated fluorination of potassium aryltrifluoroborates with Selectfluor® and potassiumfluoride is described. The fluorination reaction uses commercially available reagents and without requiring the addition of exogenous ligands. Fluorinated compounds were obtained in moderate to good yields under mild reaction conditions. The synthesis of fluorinated arenes
procedure for the copper-mediated oxidativetrifluoromethylthiolation of potassium aryl- and heteroaryltrifluoroborates with Ruppert–Prakash reagent and elementalsulfur is presented. Aryl trifluoromethyl thioethers can be prepared in good to moderate yield under mild reaction conditions.
