Direct reduction of WCl6 with PMe3 in toluene at 120°C in a sealed tube affords the complexes [WCl4(PMe3)x] (x = 2, 3). [WCl4(PMe3)3] abstracts oxygen from equimolar amounts of water in wet acetone or tetrahydrofuran to give [WOCl2(PMe3)3] in very high yields. This procedure has been successfully applied to the high yield synthesis of other known oxotungsten(IV) complexes, [WOCl2(PR3)3] (PR3 = PMe2Ph
在密封管中于120°C在
甲苯中用PMe 3将WCl 6直接还原,得到配合物[WCl 4(PMe 3)x ](x = 2,3)。[WCl 4(PMe 3)3 ]从湿
丙酮或
四氢呋喃中的等摩尔量的
水中提取
氧气,从而以非常高的收率得到[ WOCl 2(PMe 3)3 ]。此方法已成功应用于其他已知的氧
钨(IV)配合物[WOCl 2(PR 3)3 ](PR 3 = PMe 2Ph和PMePh 2)。[ WOCl 2(PMe 3)3 ]与NaX的复分解反应得到[WOX 2(PMe 3)3 ](X = NCO,
NCS)和[WOX 2(PMe 3)](X = Me 2
NCS 2)。还描述了
亚磷酸三甲
酯类似物[WOCl 2(P(OMe)3)3 ]的合成,并基于IR和1 H和31 P NMR光谱确定了新配合物的结构。
