synthetic route:

Reference yield: 19.9%

1-hexene (592-41-6,25067-06-5) + decacarbonyldirhenium(0) (14285-68-8) + 2,3-bis(diphenylphosphino)maleic anhydride (51501-24-7) → Re(CO)4[Re(CO)4(2,3-bis(diphenylphosphino)maleic anhydride)] (683249-72-1,683249-74-3) + Re2(CO)8(2,3-bis(diphenylphosphino)maleic anhydride) (683249-72-1,683249-74-3)

Guidance literature:

In dichloromethane; Irradiation (UV/VIS); under Ar atm. soln. Re2(CO)10 in 1-hexene was irradiated at 254 nm, solvent was removed in vacuo, CH2Cl2 followed by bma were added and stirred for 2 weeks protected from light; solvent was removed in vacuo, residue was extd. with petroleum ether, low-temperature (-78°C) column chromy.; elem. anal.;
