Synthesis of Tungsten Imido Alkylidene Complexes that Contain an Electron-Withdrawing Imido Ligand

[Image: see text] Tungsten NAr(R) alkylidene complexes have been prepared that contain the electron-withdrawing Ar(R) groups 2,4,6-X(3)C(6)H(2) (Ar(X3), X = Cl, Br), 2,6-Cl(2)-4-CF(3)C(6)H(2) (Ar(Cl2CF3)), and 3,5-(CF(3))(2)C(6)H(3) (Ar((CF3)2)). Reported complexes include W(NAr(R))(2)Cl(2)(dme) (dm...

description [Image: see text] Tungsten NAr(R) alkylidene complexes have been prepared that contain the electron-withdrawing Ar(R) groups 2,4,6-X(3)C(6)H(2) (Ar(X3), X = Cl, Br), 2,6-Cl(2)-4-CF(3)C(6)H(2) (Ar(Cl2CF3)), and 3,5-(CF(3))(2)C(6)H(3) (Ar((CF3)2)). Reported complexes include W(NAr(R))(2)Cl(2)(dme) (dme = 1,2-dimethoxyethane), W(NAr(R))(2)(CH(2)CMe(3))(2), W(NAr(R))(CHCMe(3))(OTf)(2)(dme), and W(NAr(R))(CHCMe(3))(ODBMP)(2) (DBMP = 4-Me-2,6-(CHPh(2))C(6)H(2)). The W(NAr(R))(CHCMe(3))(ODBMP)(2) complexes were explored as initiators for the polymerization of 2,3-dicarbomethoxynorbornadiene (DCMNBD).
