formaldehyd in tetrahydrofuran Trans-n-PrOIr(CO)(PPh3)2 and paraformaldehyde are dissolved in THF and stirred ( 2 days, room temp.).; React. is monitored by IR and NMR. Removing of solvent yields yellow solid, chromy. on Florisil (eluant: THF/cyclohexane).;
carbon monoxide; hydrogen in paraffin an autoclave containing a soln. of Ru3-cluster in parafin oil was pressurized to 500 psig with 1:1 CO-H2 and was heated at 130°C for 23 h; cooled, gases were vented through U-trap cooled by liq. N2, the contentof the trap was analyzed by mass spectrometry;
in methanol T=20°C; P=30400 Torr; electrolysis by using Cu working electrode, Pt counter electrode, Ag quasi-reference electrode, electrolyte: tetrabutylammonium tetrafluoroborate, current density: 200 mA cm-2;
