Synthesis and Characterization of Di(Alkoxy) Tripseudohalido-Tungsten(V)

Abstract

  Pseudohalide derivatives of the type (RO)₂W(Ps)₃ of (RO)₂WCl₃ have been synthesized by the interaction of (RO)₂WCl₃ with potassium pseudohalides (Ps = thiocyanate, cyanate and azide) in tetrahydrofuran ( R = Me, Et, i-Pr, n-Bu, i-Bu and t-Bu). The derivatives have been characterized by their elemental analysis, IR spectra and other physical measurements. It has been observed that the pseudohalide groups are attached to the tungsten atom through the atom with lesser electronegativity in the group.
