Reduction of tungsten(VI) and molybdenum(V) by allyltrimethylsilane and cyclopentene. Simple high yield syntheses of MoCl 4(OEt 2) 2, MoCl 4(dme), WCl 4(thf) 2, WCl 4(dme) and WOCl 3(thf) 2

Abstract

Convenient high yield methods to prepare MoCl 4(OEt 2) 2, MoCl 4(dme), WCl 4(thf) 2, WCl 4(dme) and WOCl 3(thf) 2 by reduction of MoCl 5 and WCl 6 with olefins such as allyltrimethylsilane or cyclopentene are presented.
