Synthesis of Different Cyclopolyphosphanes by Cathodic Reduction, Electrochemical Investigation of Phenyldichlorophosphane, o-, m-, p-Bromophenyldichlorophosphane and tert.-ButyldichlorophosphaneThe electrochemical properties of selected dichlorophosphanes R-PCl2 (R = C6H5, o-BrC6H4, m-BrC6H4, p-BrC6H4, t-Bu) have been investigated by the Differential-Pulse-Polarography (DPP) and by cyclic voltammetry. On the basis of the obtained results an electrolysis (cathodic reduction) has been carried out with these substances in a 1,2-dichlorethane/0.1 M tetrabutyl-ammonium tetrafluoroborate solution with a mercury pool. The following cyclopolyphosphanes have been prepared, isolated, and characterized: (C6H5P)5,(4); (o-BrC6H4P)4; (m-BrC6H4P)5,(4,6); (p-BrC6H4P)5,(4); (t-BuP)4.
Notes:
Mit Hilfe von Differential-Puls-Polarographie (DPP) und Cyclovoltammetrie wurde das elektrochemische Verhalten ausgewählter Dichlorphosphan-Verbindungen R-PCl2 (R = C6H5, o-BrC6H4, m-BrC6H4, p-BrC6H4, t-Bu) untersucht. Auf der Grundlage der erhaltenen Werte wurden diese Substanzen in einer 1,2-Dichlorethan/0,1 M Tetrabutylammonium-tetrafluoroborat-Lösung kathodisch an einem Quecksilbersee elektrolysiert. Folgende Cyclopolyphosphane wurden dabei hergestellt, isoliert und charakterisiert: (C6H5P)5,(4); (o-BrC6H4P)4; (m-BrC6H4P)5,(4,6); (p-BrC6H4P)5,(4); (t-BuP)4.
