Abstract

Reactions of WOCl4 with NaOSiPh3 and Na2O2SiPh2 gave respectively [WO (Cl)(OSiPh3) 3] and [{WO2 [(OSiPh2) 2O]} 2]. Under similar conditions NaOSiPh3 reacted with [WO2Cl2 (OSC4H8) 2] to yield [WO2 (OSiPh3) 2 (OSC4H8) 2]. The novel spirocyclic tungstasiloxane [WO {O (Ph2SiO) 3} 2 (thf)] was prepared from the reaction between equimolar quantities of (Ph2SiO) 3 and WOCl4 in tetrahydrofuran. A crystal structure determination on this product ...
