Tiivistelmä
The dioxidotungsten(VI) and -molybdenum(VI) complexes [WO2(O2NOMe)] (1), [MoO2(O2NOMe)] (2) and [{MoO2-(O2NMe)}(2)] (3) [O2NOMe methoxyethylamino-N,N-bis(2-methylene-4,6-dimethylphenolate) dianion, O2NMe = methylamino-N,N-bis(2-methylene-4,6-dimethylphenolate) dianion] can react with chloride sources (Me3SiCl, SOCl2) to form resultant monooxido dichloro compounds [WOCl2(O2NOMe)] (4), [MoOCl2(O2NOMe)] (5) and [MoOCl2(O2NMe)] (6), respectively. The reaction of tungsten complex yields of the mixture of cis-4 and trans-4, which can be separated and characterized. The reactions of analogous molybdenum complexes with Me3SiCl yield trans isomers of 5 and 6 as individual products. Reaction of dioxidotungsten complex 1 with isopropyl isocyanate was found to produce a tungsten(VI) complex [W(O2NOMe)(N-iPr)(L)] (7) (L = N,N'-diisopropylureate) with a terminal imido group and a bidentate ureate ligand.
