Abstract

The nitridotungsten(vi) complex NW(N[i-Pr]Ar)(3) (-N, Ar = 3,5-Me(2)C(6)H(3)) reacts with (CF(3)C(O))(2)O followed by ClSiMe(3) to give the isolable trifluoroacetylimido-chloride complex -(NC(O)CF(3))Cl, with oxalyl chloride to give cyanate-dichloride -(OCN)(Cl)(2), and with PCl(5) to give trichlorophosphinimide-dichloride -(NPCl(3))(Cl)(2). The oxo-chloride complex -(O)Cl, obtained from -N upon treatment with pivaloyl chloride, reacts with PCl(5) to give trichloride -(Cl)(3). Synthetic and structural details are reported for the new tungsten trisanilide derivatives.

摘要

氮钨（VI）配合物NW(N[i-Pr]Ar)(3) （-N，Ar = 3,5-Me(2)C(6)H(3)）与(CF(3)C(O))(2)O反应，随后与ClSiMe(3)反应，得到可分离的三氟乙酰亚胺氯配合物-(NC(O)CF(3))Cl；与草酰氯反应得到氰酸二氯配合物-(OCN)(Cl)(2)；与PCl(5)反应得到三氯磷酰亚胺二氯配合物-(NPCl(3))(Cl)(2)。由-N经新戊酰氯处理得到的氧氯配合物-(O)Cl与PCl(5)反应生成三氯化物-(Cl)(3)。报道了新型钨三芳基酰胺衍生物的合成和结构细节。
