Abstract

The interaction of C₇H₈Mo(CO)₄ with 2 equivalents of Ph₂P(C₅H₅) in hexane at -2°C gives two isomers of cis-[Ph₂P(C₅H₅)]₂Mo(CO)₄ (II and III) in high yield. In toluene, the coordinated Ph₂P(C₅H₅) ligands of II and III undergo intramolecular Diels-Alder dimerization at room temperature producing cis-[1,3-bis(diphenylphosphino) dicyclopentadiene](tetracarbonyl)molybdenum (IV) in quantitative yield. Compound IV can also be prepared in high yield by the interaction of cis-Mo(CO)₄(Ph₂PCl)₂ with 2 equivalents of (C₅H₅)Tl in refluxing toluene. Pyrolysis of IV gives a hexane solvate 2[(C₅H₅)Mo]₂(μ-PPh₂) ₂(CO)(O)·C₆H₁₄ (VI) in low yield, the structure of which was determined by X-ray crystallography.
