The molybdenum(VI) complex (Ar'N)2MoCl2. THF (Ar' = 2,6-diisopropylphenyl) was prepared by reaction of MoO2Cl2 With Ar'NCO at 70-degrees-C in THF. The preparations of the derivatives Mo(NAr')2Np2, Mo(NAr')2Mes2, Mo(NAr')2MesBr, Mo(NAr')2(NEt2)Cl, and Mo(NAr')2NEt2)2 from Mo(NAr')2Cl2.THF are described. In addition, the complex Mo(NAr')2(NHAr')2 has been synthesized and characterized crystallographically.

Abstract Reaction of (ArN)2MoCl2(DME) (Ar=2,6-Pri 2C6H3, DME=dimethoxyethane) with LiNMe2 and Li(THF)3Si(SiMe3)3 was found to give a Mo imide amide silyl complex (ArN)2Mo(NMe2)[Si(SiMe3)3] (1). Imide amide complexes (ArN)2Mo(NMe2)2 (2) and (ArN)2Mo(NMe2)[N(SiMe3)2] (4) were prepared from the reactions of (ArN)2MoCl2(DME) with lithium amide reagents and characterized.

The unprecedented tris(imido) complex of molybdenum, [Li(THF)4][Mo(NAr)3Cl](Ar = C6H3Pri2-2,6), is the kinetic product of the reaction between [Mo(NAr)2Cl2(THF)2] and 2 equiv. of LiNHAr in THF; [Li(THF)4][Mo(NAr)3Cl] and byproduct H2NAr react further to form the thermodynamic product [Mo(NAr)2(NHAr)2].
