I’m currently trying to write a lab report for the synthesis of dimolybdenum tetraacetate [Mo2(O2CCH3)4] from the reaction of molybdenum hexacarbonyl, Mo(CO)6 in glacial acetic acid and acetic anhydride under a nitrogen atmosphere, involving the difficult formation of a quadruple bond and requires high heat and long reaction time (approximately 20 hours). But these are the question I’m stumped on: 1. Why need the reaction be done under nitrogen? We also added dichlorobenzene and hexanes during the reaction. 2. Explain the purpose of dichlorobenzene and hexanes. 3. Why does the reaction take 20 hrs?

Tunicates are marine animals that are called "sea squirts" because when they are taken out of water, they tend to contract and expel seawater. Lepadiformine is a cytotoxic agent (toxic to cells) isolated from a marine tunicate. During a recent synthesis of lepadiformine, the investigators observed the formation of an interesting by-product (3) while treating diol 1 with a reagent similar in function to PBr3 (J. Org. Chem. 2012, 77, 3390–3400):
