Abstract

Three new imido tungsten derivatives containing bi-dentate pyrrole-amine, pyrrole-imine or ketiminate precursor were synthesized and characterized. Reacting W(N^tBu)₂(NH^tBu)₂ with two equiv of C₄H₃NH(2-CH₂NH^tBu) and C₄H₃NH(2-CHNCH₂Py) in diethyl ether and toluene generates [W(N^tBu)₂{C₄H₃N(2-CH ₂NH^tBu)}₂] (1) and [W(N^tBu) ₂{C₄H₃N(2-CHNCH₂Py)}₂] (2) in good yield. Similarly, while subjecting two equiv of (ArNCMeCHCMeOH) (Ar = 2-MeOC₆H₄) with W(N^tBu)₂(NH ^tBu)₂ in diethyl ether, affords [W(N^tBu) ₂{OCMeCHCMeNAr}₂] (3) in high yield. Single crystal X-ray structure reveals that in all three complexes the 6-coordinate W atoms belong to a distorted octahedral environment.
