| | MOLYBDENUM (III) CHLORIDE Usage And Synthesis |
| Chemical Properties | -100 mesh with 99.5% purity; purple crystal(s) [STR93] [CER91] | | Uses | Molybdenum(III) chloride reacts with tetrahydrothiophene to form complexes, which catalyze the polymerization and cyclotrimerization of alkynes. | | Definition | ChEBI: Molybdenum trichloride is a molybdenum halide. | | reaction suitability | reagent type: catalyst
core: molybdenum | | Purification Methods | Boil it with 12M HCl, wash it with absolute EtOH and dry it in a vacuum desiccator. It is a brown-red powder soluble in H2O, EtOH or Et2O and gives a blue solution in conc H2SO4. [Hein & Herzog Handbook of Preparative Inorganic Chemistry (Ed.
