The reaction of Fe(CO)2(PPh3)3 with COS in toluene results in the formation of Fe(CO)3(PPh3)2 and SPPh3. When liquefied COS is used as the solvent, Fe(S2CO)(CO)2(PPh3)2 is also formed. The analogous ruthenium complex, Ru(CO)2(PPh3)3, reacts with COS to afford Ru(CO)2(η2-COS)(PPh3)2. This COS complex reacts with additional COS to give Ru(S2CO)(CO)2(PPh3)2 and with PPh3 to give Ru(CO)3(PPh3)2 and SPPh3.
