Usage

General Description

[1,2-bis(diphenylphosphino)ethane]molybdenum tetracarbonyl, also known as Molybdenum tricarbonyl 1,2-diphenylphosphinoethane complex, is a chemical compound consisting of molybdenum, carbon monoxide, and the diphosphine ligand 1,2-bis(diphenylphosphino)ethane (dppe). This coordination complex is commonly used as a catalyst in organic synthesis and chemical transformations. The molybdenum center is coordinated with four carbon monoxide ligands, and the dppe ligand chelates to the molybdenum through its phosphorus atoms, forming a stable coordination complex. It is widely employed in the catalytic reduction of carbonyl compounds, as well as in other catalytic reactions such as alkene metathesis and carbon-carbon bond forming reactions. Additionally, it is known for its ability to undergo ligand exchange reactions, allowing for fine-tuning of its catalytic properties.

2,3-benzo-7-phosphanorbornadiene complexes: Synthesis and chemistry

The reaction of benzyne with 3,4-dimethylphosphole pentacarbonylmolybdenum complexes affords the corresponding 2,3-benzo-7-phosphanorbornadiene complexes through [4+2] cycloaddition. The condensation takes place on the less hindered side of the phosphole ring corresponding to the phosphorus substituent as shown by the X-ray crystal structure analysis of the phenyl derivative (2). The strain at the bridge of 2 (C-P-C angle ca. 80°) induces a variety of splitting reactions. Upon decomplexation by dppe at 110°C in toluene, phenylphosphinidene is generated and recovered as phenylphosphine. Upon sulfurization under the same conditions, [PhPS2] is formed and trapped as a [4+2] adduct with 2,3-dimethylbutadiene. Potassium tertbutylate attacks the bridge in THF at - 78°C and, after methylation and hydrolytic workup, yields [Ph(Me)P-(OH)Mo(CO)5].

Microwave-assisted synthesis of group 6 (Cr, Mo, W) zerovalent organometallic carbonyl compounds

The microwave-assisted synthesis of a series of compounds of the form ML(CO)4 (M = Cr, Mo, W; L = en, bipy, dppm, dppe), results in the reduction of reaction times and an increase in yields over previously published syntheses. Reaction times are reduced by a factor of 5 to over 500.

Rapid synthesis of Group VI carbonyl complexes by coupling borohydride catalysis and microwave heating

Several Group VI tetracarbonyl phosphine and tertiary amine complexes [M(CO)4 L2, M = Cr, Mo, W, L2 = 2PPh 3, dppm, dppe, dppp, dppb, bpy, phen, dppf] were synthesized in minutes in the microwave at moderate temperature, atmospheric pressure, and utilizing NaBH4 as a catalyst. The reactions were optimized by careful solvent selection. The octahedral complexes were isolated in percent yields ranging from 17 to 95. The lower temperatures, shorter reaction times, benign solvents, and lower pressures as compared to the traditional thermal syntheses provide a rapid, eco-friendly synthetic route to these common Group VI complexes.
