    Description / Table of Contents: Abstract An attempt at the synthesis of oxdiazaphospholes or oxdiazadiphospholes on the basis of phosphinic hydrazides was based on methods yielding oxdiazoles in the case of carboxylic hydrazides. It has been proved that phosphinic hydrazides are not capable of tautomerism with the hydroxyhydrazone form. Hence, the routes adopted in the investigations fail to give phospholes. The reactions involved in these experiments furnished: a) bis[dichloro-orthophosphinyl]hydrazine from bisphosphinyl hydrazines and phosphorus oxychloride; b) orthophosphinic trichlorides and tetrazines from N-phosphinyl-N′-benzoyl hydrazines and phosphorus pentachloride; c) hydrazido ester of phosphinic acid and then phosphinates in addition to esterazines, aminotriazoles and tetrazines from phosphinic hydrazides and orthoesters; and d) phosphinyl hydrazidines and then phosphinates in addition to triazoles from phosphinic hydrazides and imidoester hydrochlorides. The substituents at the phosphorus atom have a pronounced effect on the course of the reactions.
    Notes: Zusammenfassung Versuche, Oxdiazaphosphole oder Oxdiazadiphosphole aus Phosphinsäure-hydraziden nach Methoden herzustellen, die bei Carbonsäure-hydraziden Oxdiazole ergeben, führten nicht zum Ziel. Es wurde bewiesen, daß Phosphinsäure-hydrazide nicht zur Tautomerie mit der Oxyhydrazon-Form befähigt sind. In Ausweichreaktionen entstehen a) aus Bisphosphinyl-hydrazinen und Phosphoroxychlorid Bis[dichlor-orthophosphinyl]-hydrazine, b) aus N-Phosphinyl-N′-benzoyl-hydrazinen und Phosphorpentachlorid Orthophosphinsäure-trichloride und Tetrazine, c) aus Phosphinsäure-hydraziden und Orthoestern Phosphinyl-hydrazidoester und weiter Phosphinsäureester neben Esterazinen, Aminotriazolen und Tetrazinen und d) aus Phosphinsäure-hydraziden und Imidoester-hydrochloriden Phosphinyl-hydrazidine und weiter Phosphinsäureester neben Triazolen. Die Substituenten am Phosphor haben einen bemerkenswerten Einfluß auf den Ablauf der Reaktionen.

    Description / Table of Contents: Abstract Addition of trinitromethane and 1.1-dinitroethane to chloromethyl vinyl ketone, methyl 2-chloroacrylate and 2-chloroacrolein, respectively, gave di-and trinitrochloroketones and the corresponding esters and aldehydes which by reduction with corresponding esters and aldehydes which by reduction with NaBH4 furnished di-and trinitrochlorohydrins. Only 1-chloro-5.5-dinitrohexanol-(2) when treated with alkalies gave an epoxide, the 5.5-dinitrohexene-1-oxide. 5-Chloromethyl-2.2-dinitrotetrahydrofuran was obtained from 1-chloro-5.5.5-trinitropentanol-(2) by abstraction of a nitrite ion and cyclization.
    Notes: Zusammenfassung Durch Addition von Nitroform bzw. 1,1-Dinitroäthan an Chlormethylvinylketon, 2-Chloracrylsäuremethylester bzw. 2-Chloracrolein wurden. Di-und Trinitrochlorketone,-ester und-aldehyde erhalten, die durch Reduktion mit NaBH4 Di-bzw. Trinitrochlorhydrine ergaben. Nur 1-Chlor-5,5-dinitro-hexanol-(2) ergab bei Behandlung mit Alkalien ein Epoxid, das 5,5-Dinitrohexen-1-oxid. Aus 1-Chlor-5,5,5-trinitropentanol-(2) entstand unter Abspaltung eines Nitritions und Cyclisierung 5-Chlormethyl-2,2-dinitrotetrahydrofuran.

    Synthese und Hydrolyse von 1,3-Dihydro-1,3,2-benzodiazaphosphol-2-oxiden (1966)

    Description / Table of Contents: Abstract Various 1.3-dihydro-1.3.2-benzodiazaphosphole-2-oxides and the corresponding bis phosphole oxides have been prepared. Some of the compounds allowed to be prepared in satisfactory yield and high purity only in the absence of solvents at temperatures up to 250°C. Hydrolysis usually entailed cleavage of the two P−N-bonds, and interaction with the diamine yields the monosalt of phosphonic acid; this salt is identical with that obtained by direct interaction of the two reactants.
    Notes: Zusammenfassung Verschiedene 1,3-Dihydro-1,3,2-benzodiazaphosphol-2-oxide und entsprechende Bisverbindungen wurden hergestellt. Einige der Verbindungen konnten nur ohne Lösungsmittel bei Temperaturen bis zu 250°C in guter Ausbeute und in großer Reinheit erhalten werden. Bei der Hydrolyse werden meist beide P−N-Bindungen gespalten, und es entsteht das Monosalz der Phosphonsäure mit dem Diamin; dieses Salz ist identisch mit dem aus den beiden Komponenten direkt erhaltenen.
