Synthesis, characterization, and properties of the η2-acyl complexes Mo(η2-COCH2CMe3)X(PMe3) 4 (X = Cl, Br)

The η2-acyl complexes of molybdenum Mo(η2-COCH2CMe3)X(PMe3) 4 (X = Cl (1a), Br (1b)) have been prepared by the action of Mg(CH2CMe3)X on the carbonyl carbonate Mo(CO3)(CO)(PMe3)4. Complex 1 decomposes in solution with dissociation of PMe3. This reaction occurs faster in the presence of small amounts of water (2-3 drops) with formation of the hydroxo species [MoX(CO)(PMe3)2(μ-OH)]2 (X = Cl (2a), Br (2b)). Carbonylation of 1a, at room temperature and pressure, affords successively Mo(η2-COCH2CMe3)Cl(CO)(PMe 3)3 and Mo(η2-COCH2CMe3)Cl(CO)2(PMe 3)2. Finally, the reaction of Mo(CO3)(CO)(PMe3)4 with CH2Cl2 yields the 7-coordinate anionic compound MoCl3(CO)(PMe3)3, which is isolated as the tetramethylphosphonium salt, [PMe4][MoCl3(CO)(PMe3)3] (3). The crystal structure of 1b has been determined by X-ray crystallography. It crystallizes in the orthorhombic space group, P212121, with a = 10.021 (2) A?, b = 16.752 (3) A?, c = 16.855 (5) A?, and Dcalcd = 1.36 g cm-3 for Z = 4. A total of 1098 independent observed [Fo > 5σ(Fo)] reflections were used in the least-squares refinement, which led to a final conventional R value of 0.051. The molybdenum atom has an approximate pentagonal-bipyramidal geometry, the η2-acyl ligand residing in the pentagonal plane. The acyl and bromo ligands are trans; important distances include Mo-Br = 2.687 (5) A?, Mo-C = 2.00 (3) A?, Mo-O = 2.21 (2) A?, and Mo-P = 2.48 (4) A?, average.
