WebAlkali metal additives enhance the rate of CF3 transfer from borazine, while the opposite effect is observed for (MeO)3BCF3K which is likely due to the Lewis-basic methoxide groups on the later. In order to generate fluoroalkylation reagents that are more specifically suited towards catalysis, we synthesized and characterized 3 neutral ... WebThis study reports geminal amino- and oxy-trifluoromethylation of ortho-ethynyl anilines/phenols by phenCu(III)(CF3)3 (phen denotes 1,10-phenanthroline), which constructs indole and benzofuran skeleton with concurrent incorporation of a CF3 group to the C2 position. ...
