complexes of tungsten(VI), [WCl4CHR[C6H2(But)2O]2}] R = H (1), Me (2) are reduced by Na/Hg in the presence of PMe3 to give cis, trans-WCl2(PMe3)2CHR[C6H2(But)2O]2} R = H (3), Me (4). Reaction of [WOCl4] with the biphenols 2,2′-CHR[C6H2(But)2OH]2 in diethyl ether gives [WOCl2CHR[C6H2(But)2O]2}] R = H (5), Me (6). Similar treatment of [W(NPh)Cl4(Et2O)] gives the complex [W(NPh)Cl3(1,1′-O,OH)(2,2′-CH3CH)[4
钨(VI),[WCl 4 CHR [C 6 H 2(Bu t)2 O] 2 }] R = H(1),Me(2)的Biphenoxo配合物在存在PMe的情况下被Na / Hg还原3,得到顺式,反式-WCl 2(PME 3)2 CHR [C 6 H ^ 2(BU吨)2 O] 2 } R = H(3)中,Me(4)。[WOCl 4 ]与双酚2,2'-CHR [C 6 H在乙醚中的2(Bu t)2 OH] 2得到[WOCl 2 CHR [C 6 H 2(Bu t)2 O] 2 }] R = H(5),Me(6)。对[W(NPh)Cl 4(Et 2 O)]进行类似处理,得到复合物[W(NPh)Cl 3 (1,1'-O,OH)(2,2'-CH 3 CH)[4, 6-(卜吨)2 c ^ 6 ħ 2 ] 2 }](7含有单阴离子配体(1,1'- O,OH)(2,2'-CH)3 CH)[4,6-(卜t)
