Preparation and properties of some pyrazolyl ketones

Autor: T. Foster, I. L. Finar

Publikováno v: Journal of the Chemical Society C: Organic. :1494

Friedel–Crafts acylation reactions of some N-methyl and N-phenylpyrazoles have been investigated and some phenyl pyrazolyl ketones and dipyrazolyl ketones have been prepared. Substitution occurred at the 4-position in the pyrazole nucleus, an excep

The Beckmann rearrangement of some pyrazolyl oximes

Autor: H. E. Saunders, I. L. Finar

Publikováno v: Journal of the Chemical Society C: Organic. :1495

The oximes of several pyrazolyl carbonyl compounds have been prepared, in some cases both as syn- and anti-isomers. They have been subjected to the Beckmann rearrangement with phosphorus pentachloride, toluene-p-sulphonyl chloride, concentrated sulph

Reactions of 1-phenylpyrazol-4-ylmagnesium bromide. Part II

Autor: R. J. Brooklyn, I. L. Finar

Publikováno v: Journal of the Chemical Society C: Organic. :1515

1-Phenylpyrazol-4-ylmagnesium bromide reacts with bromide and iodine to give the corresponding 4-halogeno-pyrazole, and with iodine chloride and iodine bromide to give 4-iodo-1-phenylpyrazole, similar yields of which are obtained by the direct iodina
