in cyclohexane byproducts: Ru3(CO)12; Irradiation (UV/VIS); Ru5(CO)14S2 dissolved in cyclohexane was combined with a soln. Ru(CO)5 in cyclohexane, the soln. was irradiated for 10 h at 25°C under N2; the soln. was concd. and chromd. with hexane, obtained Ru3(CO)12, then eluted with hexane/CH2Cl2, this was further purified by TLC using a hexane/CH2Cl2 mixt.; elem. anal.;

With  CO in  hexane  Ru5(CO)14S2 was dissolved in hexane, vigorously stirred, CO was bubbled through it at 25°C for 15 min; filtered;
