Synthesis of mono- and ditungstaboranes from reaction of Cp*WCl4 and [Cp*WCl2](2) with BH3 center dot thf or LiBH4 (Cp* = eta(5)-C5Me5). Control of reaction pathway by choice of monoboron reagent and oxidation state of metal center

Abstract:

Reaction between Cp*WCl4 or [Cp*WCl2]2 (Cp*= η5·C5Me5) and BH3·thf affords the new tungstaborane (Cp*WCl)2B2H6, 2, which reacts with further BH3·thf to give (Cp*W)2B5H9, 1. The structure of 1 has been determined by a single-crystal X-ray diffraction study and is best described as a bicapped trigonal bipyramidal, the same as previously found for Cr and Mo analogues. The first step of this reaction is reduction of Cp*WCl4 to [Cp*WCl2]2 by BH3· thf, paralleling that of the Cp*MoCl4 system. In co...
