The reaction of Fe(CO)2(η2-CS2){P(OPh)3} 2 1 with two equivalents of PBu3 in a minimum volume of a polar solvent such as acetonitrile or dimethylsulfoxide afforded the thiocarbonyl derivative Fe(CO)2(CS){P(OPh)3}} 2 in ca. 80% yield whereas reaction in solvents such as dichloromethane or benzene afforded the substitution products Fe(CO)2(η2-CS2){P(OPh) 3}(PBu3) and Fe(CO)2(η2-CS2)(PBu3) 2. Although desulphurization of Fe(CO)2(η2-CS2){P(OR)3} 2 by PBu3 in polar solvents is not a general route to Fe(CO)2(CS){P(OR)3}2 for all R, the new compound Fe(CO)2(CS){P(OEt)3}2 has been obtained and characterised spectroscopically. The crystal structures of 2 and Fe(CO)3{P(OPh)3}2 were determined and are very similar. Both compounds are trigonal bipyramidal about the Fe atom with trans apical phosphite ligands and a trigonal planar arrangement of CO/CS groups. The CS ligand in 2 was found to be disordered over two sites with occupancies 0.63 and 0.37.

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.
