Abstract:Die fünfgliedrige Kette eines Bis‐(trichlorphosphazo)‐methyl‐hexachloroantimonats kondensiert mit NH4Cl unter Ringschluß zum 3‐substituierten Tetrachlor‐diphosphatriazin VI, mit dem Hydrochlorid eines primären Amins zum 3,6‐disubstituierten Tetrachlordiphosphatriazinium‐hexachloroantimonat IV. Die 31P1H‐Kopplung in IV wird im Hinblick auf die Änderung der Winkel‐ und Bindungsverhältnisse beim Ringschluß diskutiert.
“…From a study of the prototropic equilibrium between aminophosphines R 2 P-NHR and hydridophosphazenes R 2 PHסNR, we obtained additional cyclic and acyclic examples of the latter, such as 8 and 9 [18][19][20][21][22][23][24][25][26][27][28][29][30]. 31 P NMR spectroscopy was very new at that time, and we tried to learn more about the chemical shifts from systematic investigations [31][32][33][34][35][36].…”

“…The dimer 66, trimer 67, and tetramer 68 of the ylidediyl chlorophosphine Ph 3 PCPCl constitute another, rather multiform family of heterocycles [175][176][177][178], and the choroarsine oligomers parallel them perfectly [161].…”

“…Of the tin derivatives [18][19][20], I remember, in particular, a tris(imidodiphosphinato)tin chloride. It completely decolorizes an aqueous KMnO 4 solution and becomes the permanganate 5, which can be isolated as purple crystals.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
