Diethoxy- phosphane

Impure ethyl(diethoxy)phosphane telluride was obtained as an unstable yellow liquid by heating ethyl(diethoxy)phosphane and tellurium1 or reacting dichloroethylphosphane with ethanol and tellurium in benzene in the presence of triethylamine2. Dichloromethyl-phosphane did not react with tellurium3. [Pg.25]

Die Herstellung von Phosphinsauren aus Phosphonigsaure-diestern ist auch durch Addition der Letzteren an aktivierte C=C-Bindungen und Verseifung der primaren Reak-tionsprodukte moglich. Auf diese Weise ist z. B. (2-Amino-2-carboxy-ethyl)-methyl-phos-phinsaure aus Diethoxy-methyl-phosphan mit 2-Acetylamino-acrylsaure zuganglich68. [Pg.134]

Erwahnenswert ist die Umsetzung von Diethoxy-phenylethinyl-phosphan mit Michaelis-Arbuzov-Produkt) ... [Pg.204]

Methyl-(2-nitro-phenyl)-phosphinsaure-ethylester550 Eine Lbsung von 6,15 g(37,l mmol) 1,2-Dinitro-benzol und 9,20 g (67,6 mmol) Diethoxy-methyl-phosphan in 120 ml Acetonitril wird 20 Stdn. bei 18°belassen. Nach Abziehen des Losungsmittcls wird destilliert Ausbeute 6,50 g (77%) Sdp. 130°/0,0075 Torr (1 Pa). [Pg.208]

Trifluorovinylmagncsium iodide couples with chloro(diethoxy)phosphanc to give the trifluoro-vinylphosphane 32 in moderate yield and phenylbis(trifluoromethyl)phosphane (34) can be obtained by reacting chlorbis(trifluoromethyl)phosphanc (33) with phenylmagnesium bromide. ... [Pg.661]
