(Norbornadiene)molybdenum tetracarbonyl is the organomolybdenum compound with the formula (C₇H₉)Mo(CO)₄. Structurally, the compound consists of the norbornadiene bonded to a Mo(CO)₄ fragment. The compound is a yellow, volatile solid. It is prepared by thermal or photochemical substitution of molybdenum hexacarbonyl.[1] The compound was originally examined as a potential antiknock agent.[2]

(Norbornadiene)molybdenum tetracarbonyl is a precursor to other derivatives of the type L₂Mo(CO)₄. This conversion exploits the lability of the diene ligand:[3]

(C₇H₉)Mo(CO)₄ + 2 L → C₇H₉ + L₂Mo(CO)₄
