TL;DR: In this article, it was shown that the analogous 1/1-complexes of (CH 3 ) 3 P&.zdbndNSi(CH 3 2 N 2 -N& N& N 2 −N&N&P(CH3 ) 3 exhibit a nonrigid behavior as shown by the temperature dependence of the 1 H NMR spectra.

TL;DR: Ammonim-N-phosphinylimine was prepared from the corresponding hydrazinium salt as discussed by the authors, which gave phosphinylnitrenes on thermolysis, predominantly in the singlet state.
Abstract: Ammonim-N-phosphinylimine was prepared from the corresponding hydrazinium salt. The ylid gave phosphinylnitrenes on thermolysis, predominantly in the singlet state. On photolysis, the ylid also gave a singlet product.

TL;DR: In this paper, Nacylated Thiophosphinic Amides (N-thioacyl)-and N-sulfonyl-substituted amides are prepared by the reaction of metallated acid amides with acid chlorides.
Abstract: N-Acyl-, N-Thioacyl- und N-Sulfonyl-substituierte Thiophosphinsaureamide werden durch Reaktion metallierter Saureamide mit Saurechloriden erhalten. Die Verbindungen liegen als Imide vor und bilden im festen Zustand intermolekulare Wasserstoffbrucken. Ihre potentiometrisch bestimmten Aciditatskonstanten zeigen einen betrachtlichen acidifizierenden Einflus der Thiophosphinylreste an. Die Methylierung mit Diazomethan fuhrt hauptsachlich zu S-Methylestern der Imidothiophosphinsauren.
Preparation and Properties of N-acylated Thiophosphinic Amides
N-Acyl-, N-thioacyl- and N-sulfonyl-substituted thiophosphinic amides are prepared by the reaction of metallated acid amides with acid chlorides. The compounds exist as imides and form intermolecular hydrogen bonds. Their pKa-values were potentiometrically determined and show a considerable acidifying influence of the thiophosphinic residues. Methylation of the imides with diazomethan gives predominantly S-methylesters of imidothiophosphinic acids.
