Molybdenum hexacarbonyl is a popular reagent in academic research. [6]One or more CO ligands can be displaced by other ligands. [7] Mo(CO) 6, [Mo(CO) 3 (MeCN) 3], and related derivatives are employed as catalysts in organic synthesis for example, alkyne metathesis and the Pauson–Khand reaction.
Mo(CO) 6 reacts with arenes to give piano-stool complexes such as (mesitylene)molybdenum tricarbonyl. Cycloheptatrienemolybdenum tricarbonyl, which is related to (arene)Mo(CO) 3, reacts with trityl salts to give the cycloheptatrienyl complex: [3] (C 7 H 8)Mo(CO) 3 + (C 6 H 5) 3 C + → [(C 7 H 7)Mo(CO) 3] + + (C 6 H 5) 3 CH Structure of ...
The molecular mass (for molecular compounds) and formula mass (for non-molecular compounds, such as ionic salts) are commonly used as synonyms of molar mass, differing only in units (daltons vs g/mol); however, the most authoritative sources define it differently. The difference is that molecular mass is the mass of one specific particle or ...
W(CO) 6 behaves similarly to the Mo(CO) 6 but tends to form compounds that are kinetically more robust. Cyclopentadienyltungsten tricarbonyl dimer ((C 5 H 5.) 2 W 2 (CO) 6) is produced from W(CO) 6. Treatment of tungsten hexacarbonyl with sodium cyclopentadienide followed by oxidation of the resulting NaW(CO) 3 (C 5 H 5) gives ...
It's compact and lightweight at 2.6 pounds, and our price trackers tell us it's only dipped $1 lower all year. "I’m obsessed with this vacuum!" gushed a buyer. "It's so lightweight, has GREAT ...
The six CO ligands are terminal and the Mo-Mo bond distance is 3.2325 Å. [2] The compound is prepared by treatment of molybdenum hexacarbonyl with sodium cyclopentadienide followed by oxidation of the resulting NaMo(CO) 3 (C 5 H 5). [3] Other methods have been developed starting with Mo(CO) 3 (CH 3 CN) 3 instead of Mo(CO) 6. [4]
