An Unconventional Mechanistic Insight into SCF<sub>3</sub>Formation from Difluorocarbene: Preparation of<sup>18</sup>F-Labeled α-SCF<sub>3</sub>Carbonyl Compounds
trifluoromethyl anion‐based theory. Mechanistic elucidation reveals an unprecedented chemical process for the formation of thiocarbonyl fluoride and also enables transition‐metal‐mediated trifluoromethylthiolation and [18F]trifluoromethylthiolation of α‐bromo carbonyl compounds with broad substrate scope and compatibility.
