ultimately produced then their formal products of dehydration: di(t-butyl) or diphenylallenylidene(dicarbonyl)bis(triethylphosphine)iron compounds 4a or 4b. The reactions of dicarbonylbis(trimethylphosphite)iodoferrate 1b with the same propargyl alcohol derivatives HC≡C-CR1R2OH as mentioned above resulted in the formation of dicarbonylbistrimethylphosphite(vinylidene)iron derivatives Fe(CO)2[P(OMe)3]2 =C=C(H)CR1R2OH
