Darstellung und chemisches Verhalten aliphatischer und cycloaliphatischer Diphosphine, R2PPR2

Abstract: Aliphatische und cycloaliphatische Chlorphosphine, RzPCI, FUr die ein allgemein anwendbares Darstellungsverfahren beschrieben wird, reagieren mit Natrium in Dioxan unter Bildung von Diphosphinen, R2P-PR2. Auf diese Weise werden aus (CzH5)2PCI, (C4H&PCI und (C6H1 I)~PCI die Verbindungen stellt, die sich mit Schwefel bzw. Sauerstoff zu den entsprechenden Disulfiden, R2P(S) -P(S)R2, bzw. Dioxyden, R2P(O) -P(O)Rz, vereinigen. Die Tetraalkyldiphosphine lagern ein Mol. Alkylhalogenid unter Bildung von Pentaalkyldiph… Show more

“…In accordance with expectation, the difluorophosphines RPF 2 (R = tert.-Bu, Ph) were the only phosphorus compounds observed by 31 P NMR spectroscopy when solutions of 1 and 2 were treated with equimolar quantities of AlCl 3 (Scheme 1). Surprisingly, in the case of 3 a spontaneous and selective reaction took place, too.…”

“…When solutions of TrtRPF 3 were treated with iodine in a 2 : 1 ratio, in the case of 1 and 2 the formation of equimolar mixtures of RPF 4 and RPF 2 (with TrtI as by-product) was observed by 31 P NMR spectroscopy (Scheme 1). We assume the formation of an intermediate RPF 2 I 2 in the first step by oxidation of free RPF 2 by iodine.…”

“…60-62" (0.6 mm) from phosphorus tricliloride and diethylamine as previously described (18). The chloropliospliine (14.5 g) in ether (25 ml) was added dropwise to (C6H5)2PC--CLi (from ( C 6 H 5 ) 2 P C~C H (15.0 g) + r1-CJH9Li (36 ml of 2 M ) ) in ether/hexane at -78'.…”

“…HBr zunächst zuMe2NPFHal um, und Me2NPClF reagiert mit HBr schheßlich zum PBrClF [6]. Durch P-NSpaltungsreaktionen gelangt man außerdem auf bequeme Weise zu Halogenophosphanen, die sonst nur auf Umwegen oder mit schlechteren Ausbeuten gewonnen werden können: Me2PCl [7], R2PC1 [8] und J-BuMePCl [9] sind dafür beispielhaft. Außer-dem wird in diesem Zusammenhang in der Literatur noch über CF3PC12 [10], (Me2N)2PBr [11], pMeO-C6H4-PCl2 [12] sowie C6F5P(R)Hal (Hai = Cl, Br) [13] berichtet.…”
