Preparation and Substitution Chemistry of [Bu4N]2[W6Cl8(p-OSO2C6H4CH3)6]. A Useful Precursor for Pseudohalide, Acetate, and Organometallic Complexes Containing the {W6Cl8}4+ Core

The tosylate (p-toluenesulfonate) cluster [Bu4N]2[W6Cl8(p-OSO2C6H4CH3)6] (1) has been prepared and characterized by IR and NMR spectroscopy, elemental analysis, and an X-ray crystal structure. This cluster complex is shown to be a useful starting material for the preparation of pseudohalide clusters...

Description
Summary:The tosylate (p-toluenesulfonate) cluster [Bu4N]2[W6Cl8(p-OSO2C6H4CH3)6] (1) has been prepared and characterized by IR and NMR spectroscopy, elemental analysis, and an X-ray crystal structure. This cluster complex is shown to be a useful starting material for the preparation of pseudohalide clusters, [Bu4N]2[W6Cl8(NCQ)6] (Q = O (2), S (3), and Se (4)), in high yields. Cluster 1 also serves as a precursor to the new cluster commpounds:  [Bu4N]2[W6Cl8(O2CCH3)6] (5), [Bu4N]2[W6Cl8{(μ-NC)Mn(CO)2(C5H5)}6] (6), [W6Cl8{(μ-NC)Ru(PPh3)2(C5H5)}6][ p-OSO2C6H4CH3]4 (7), and [W6Cl8{(μ-NC)Os(PPh3)2(C5H5)}6][ p-OSO2C6H4CH3]4 (8). X-ray crystal structures are reported for 1, 4, and 5.
