K2Fe(CO)4 in ethanol 1 h; Ambient temperature; Yields of byproduct given;

potassium hydroxide in ethanol to a soln. of K2Fe(CO)4, prepd. from Fe(CO)5 and KOH in EtOH, was addeddropwise allyl phosphate, mixt. was stirred at room temp. for 1 h; reaction mixt. was distilled to dryness at atm. pressure at give Me2C=CHMe as distillate (GLC anal.), residue was chromd. on SiO2 (light petroleum as eluent) and distilled in vacuo to afford Fe-complex; identified by comparison with authentic sample;
