methanol in methanol Irradiation (UV/VIS); solid carbene complex is added to an oven-dried Pyrex pressure tube, followed by dry methanol, contents are degassed, purged with Ar, warmed to room temp., purged with CO, pressurized with 50-90 psi CO, irradiated (450 W) for 6 d; monitored by TLC, mixt. is filtered (Celite), evapg. in vacuo yields pure product; NMR, IR, elem. anal.;
