5-endo-dig Cyclisations of N-nitroso derivatives of homopropargylic amines, catalysed by silver nitrate on silica gel proceed smoothly at ambient temperature in chlorinated solvents to give essentially quantitative yields of the corresponding pyrazole-N-oxides, deoxygenation of which gives excellent yields of the related N-alkylpyrazoles in a regiospecific manner.
