Alkali-Phosphorverbindungen und ihr Reaktives Verhalten LXXV1 Cyclomonoheterophosphine

Abstract
Organoelement halides of the general formula R2'ECl2 (E = C, Si, Ge, Sn; R′ = H, Me, Et, n-Bu) and other compounds such as SCl2, (C5H5)2 TiCl2 and ZnCl2 react with alkali-phosphides RMP- (RP)n -PMR (n = 1,2; R = Ph, Cy; M = Na, K) forming the corresponding 1,2,3,4-tetraorgeno-cyclo-element-1,2,3,4-tetraphosphines. Polymeric and metalhalogen exchange products are obtained in the case of RECl2 (E = Al, N, As, Sb) and transition element halides, respectively. The five-membered ring structure of the title compounds is confirmed by their molecular weight and 31P-nmr-spectra.
