Versuchsvorschrift
A reaction of 4-t-butylcyclohexanone (2 mmol) with diethylaminosulfur trifluoride (3.0 mmol) in CH2Cl2 (10 mL) at room temperature gave a 99% conversion of starting material to products and a 67% yield of 1,1-difluoro-4-t-butylcyclohexane after 6 h. as determined by NMR (4-fluoroanisole as internal standard).
