Abstract
Derivatives of 3 : 5-dioxopyrazolidine, of the general formula <FORM:0806759/IV (b)/1> wherein R represents a primary or secondary hydrocarbon radical containing at least 2 carbon atoms, which may be interrupted by hetero atoms and may be substituted by hydroxy or oxo groups, and Aryl represents an unsubstituted or substituted phenyl radical, are manufactured by reacting the corresponding compounds unsubstituted in the 4-position with an alcohol R-OH in the presence of a hydrogenation catalyst. Examples describe the preparation, from the appropriate starting materials in the presence of spongy nickel catalyst, of 4-n-butyl-, 4-benzyl-, 4-cyclohexyl-, 4-n-hexyl-, 4-ethyl-, 4-isopropyl-, 4-(41-hydroxybutyl)-, 4-n-dodecyl- and 4-octadecyl-1 : 2-diphenyl - 3 : 5 - dioxopyrazolidine, and of 1 - (p - hydroxy- and p-benzyloxy-phenyl)-2-phenyl-4 - n - butyl - 3 : 5 - dioxopyrazolidine. Additional alcohols specified are n-propyl, isobutyl, sec.-butyl, n-amyl, isoamyl, b -ethylhexyl, hexadecyl, b -phenylethyl, g -phenylpropyl and cinnamyl alcohols, benzhydrol, methoxyethyl, butoxyethyl and ethoxyethoxyethyl alcohols, ethylene, propylene and trimethylene glycols, 1 : 3-butanediol, butanol-4-one-2, benzoin, dimethylaminopropanol and diethylaminoethanol. Reference has been directed by the Comptroller to Specifications 727,405, 773,022, 775,925, 781,438 and 781,439.
