摘要：

Reactions of [W(NBu(t))2(NHBu(t))2] (1) with ROH (R = Pr(i), Bu(t), CPh3) gave [W(N Bu(t))(OPr(i))4] (2), [W(NBu(t))(OBu(t))4] (3) and [W(NBu(t))2(OCPh3)2] (4). Reaction of WOCl4 with Bu(t))(Me3Si)NH gave [WO(NBu(t))(NHBu(t))Cl(NH2Bu(t))] (5) which was converted to [WO(N Bu(t))(OBu(t))2(NH2Bu(t))] (6) with trace amounts of [W(NBu(t))(OBu(t))3Cl(NH2Bu(t))] (7) by reaction with Bu(t)OH. Compound 7 was structurally characterized by single crystal X-ray crystallography. It has a distorted octahedral structure with the tertbutylimido (WN = 1.740 angstrom) and tertbutylamine (WN = 2.429 angstrom) trans to each other, with the three tertbutoxy (WO = 1.897, 1.864, 1.892 angstrom) and chloride (WCl = 2.503 angstrom) ligands in the equatorial plane. Compound 5 reacted with PMe3 to give [WO(NBu(t))2(PMe3)] (8).
