Auch andere Arbeitsgruppen haben sich mit dieser Substanzklasse beschäftigt und entsprechende Verbindungen, die zwei Hydrazineinheiten im Sechsring enthalten und Derivate der phosphorigen Säure oder von Phosphonsäuren sind dargestellt [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Formation of a diazadiphosphetidine from the reactions of a bis(aminosilyl) ether with PCl3: crystal structure of cis-[(ButNH)PNBut]2

“…2 Similar silazoxy heterocycles with P V as part of the ring framework were also prepared by reactions of phenoxy thiophosphoryl dihydrazide and phenoxy phosphoryl dihydrazide with tetraalkyl-1,3-dichlorodisiloxanes and structurally characterized. 8 Reactions of O[SiMe 2 N(R)H] 2 with PCl 3 have been reported briefly as leading to only polymeric products which were not properly identified. 1 In our attempts to make silazoxyphosphines with varying ring sizes and substituents on silicon, nitrogen and phosphorus, we observed for the first time that instead of cyclization to form a six-membered silazoxyphosphine, O[SiMe 2 N(Bu t )H] 2 cleaves at the Si᎐N bonds and forms the diazadiphosphetidine cis-[(Bu t NH)PNBu t ] 2 2.…”
