W2(OPri)6(py)2(WW)(py = pyridine) and acetone (1 equiv.) react in hydrocarbon solvents at ambient temperatures to yield tetramethylethylene and W4O2(OPri)12 the latter of which is shown, by an X-ray study, to be an unusual cluster type in which the eight electrons available for M–M bonding are partitioned into an M–M triple and M–M single bond.
w ^ 2(OPR我)6(PY)2(w ^ w ^)(PY =吡啶)和丙酮(1当量)在烃溶剂中在环境温度下进行反应,得到四甲基和W 4 ö 2(OPR我)12,后者的通过X射线研究表明,这是一种不寻常的簇类型,其中可用于M–M键的八个电子被划分为M–M三键和M–M单键。
