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.
