Abstract: | P(SiMe2)3P Li3P (produced from the elements) forms with Me2SiCl2 at 20°C in toluene the bicyclic compound P(SiMe2)3P 4 beside small amounts of ClMe2Si? P(SiMe2)2P? SiMe2Cl and traces of P4(SiMe2)6 7. 4 can be transformed into 7 by thermal treatment. With the formation of 4 the existence of a bicyclic silylphosphane is confirmed which has already been mentioned in connection with P(SiEt2)3P 1], but could not be proven until now. |
