The interaction of Li2W(N-t-Bu)4 with PhSCl gave W(N-t-Bu)2(η2-PhSN-t-Bu)2 the structure of which has been determined by X-ray diffraction; reaction of Li(PhSN-t-Bu) with transition-metal halides allows the synthesis of a range of other compounds with the η2-N,S ligand.

The interaction of TiCl4 with LiN(Bu1)SR (R = Ph or C6H2Me3-2,4,6) gave the sulfenamido complexes TiCl2(η2-ButNSR)2. Interaction of ZrCl4 with 3 equivalents of LiN(But)SPh produced ZrCl(η2-ButNSPh)3 while ZrCl4(tht)2 (tht = tetrahydrothiophene) with 5 equivalents gave the homoleptic Zr(η2-ButNSPh)4. From ZrCl2(η5-C5H5)2 only ZrCl(η5-C5H5)2(η 2-ButNSPh) 5 is obtained. Using as starting materials MO2Cl2(dme) (dme = 1,2-dimethoxyethane, M = Mo or W), MoCl2(NBut)2 and WCl2(NBut)2(py)2 (py = pyridine), interactions with LiNButSPh gave η2-sulfenamido compounds such as MoO2(η2-ButNSPh)2. The selenium analogue of the tungsten compound, i.e. W(NBut)2(η2-ButNSePh) 2 has been made by interaction of Li2W(NBut)4 with PhSeBr. Where study was possible, NMR spectra over a temperature range indicate that invertomers and isomers occur. Six compounds have been structurally characterised by X-ray diffraction. In all cases the sulfenamido ligands are η2 bonded and the geometry about the N atoms is planar.
