in tetrahydrofuran byproducts: CO; 3-fold excess Fe2(CO)9 in THF with ((p-MeO)C6H4PS2)2 were stirred at room temp., after 2 h, solvent removed at reduced pressure, residue transferred to a cooled (-10°C) SiO2 column; elution with hexane/CH2Cl2 (2/1) produced 4 compds.; the products were once again chromd. (hexane/ether 5/1) and finally recrystd. from ether/pentane mixtures (-30°C) to give the pure compounds; elem. anal.;
