Abstract

Reduction of (η-C₅Me₄R)TaX₄(R = Me, Et; X = Cl, Br) with two equivalents of sodium amalgam in toluene affords the reactive tantalum–tantalum doubly-bonded species (η-C₅Me₄R)₂Ta₂(µ-X)₄ in 70% yield; the solid-state structure of (C₅Me₅)₂Ta₂(µ-Br)₄ consists of a TaTa double bond, 2.748(2)Å in length, bridged symmetrically by four bromide ligands.
