Abstract

Abstract: Synthesis and characterization of molybdenum bisimido complexes featuring the extremely bulky Pr* framework [Pr* = 2, 6‐bis(diphenylmethyl)‐4‐methylphenyl] are reported. The octahedral halide complex [Mo(NPr*)2 Cl2 (THF)2 ] (1 ) is readily available from ammonium dimolybdate and the amine Pr*NH2, and features two THF molecules in the coordination sphere of molybdenum. The chloride ligands in1 may be exchanged with methyl or benzyl groups using Grignard reagents. The resulting complexes [Mo(NPr*)2 Me2 ] (2 ) and [Mo(NPr*)2 Bz2 ] (3 ) are monomeric and, in contrast to1, do not coordinate further neutral two‐electron donor ligands in neither the solid state nor in solution.
