## Abstract Reactions of DNBF with a series of 2‐aminothiazoles (**1 a**–**f**) to afford thermodynamically stable __C__‐bonded σ‐adducts have been investigated in acetonitrile. A most significant finding emerged on recording NMR spectra immediately after mixing of equimolar amounts of DNBF and the
