Synthesis of N ‐Nitroso CHF 2 ‐Pyrazolines and Their Transformation into CHF 2 ‐Isoxazolines and ‐Pyrazoles

Synthesis of N ‐Nitroso CHF 2 ‐Pyrazolines and Their Transformation into CHF 2 ‐Isoxazolines and ‐Pyrazoles

N ‐Nitroso CHF 2 ‐pyrazolines were synthesized from in situ generated difluoromethyldiazomethane (CF 2 HCHN 2 ), tert ‐butyl isonitrite ( t BuONO), and alkenes. The synthesis of representative CHF 2 ‐pyrazoles and CHF 2 ‐oxazolines was also performed.
