synthetic route:

Reference yield: 9.0%

sodium tetracarbonyl cobaltate (14878-28-5) + 1,2-bis(diphenylphosphino)ethane nickel(II) chloride (14647-23-5) → Ni(CO)2{1,2-bis(diphenylphosphino)ethane} (15793-01-8) + di-μ-carbonyl-1,2-bis(diphenylphosphino)ethanetetracarbonyldicobalt(0)(Co-Co) (1145354-68-2,57138-96-2)

Guidance literature:

In toluene; dried solid NaCo(CO)4 was added under N2 to a soln. of NiCl2(dppe) in toluene at -30°C, mixt. was stirred for 3 h, reaction was monitored by IR spectroscopy; filtered at -78°C, hexane was added to the filtrate, ppt. purified by column chromy. on SiO2 (eluent hexane) and crystd. to give Ni(CO)2(dppe) (elem. anal., IR data), mother liquor gave Co2(CO)6(dppe) after crystn. at -78°C (elem. anal.);
