摘要

The mechanism of carbonylation of alkyl halides using Fe(CO) _3(NO)- has been studied using density functional theory (DFT). Our results suggest an S_N2 mechanism for the alkylation event followed by a well-defined oxidative addition and alkyl migration. An experimentally elusive common intermediate Fe(CO)_2NO(Ac) has been identified in two isomers and reacted in silico with a number of ligands (CO, PH_3 and PPh_3) to give the corresponding iron acyl complexes. Pathways between the two isomers, including direct involvement of a solvent molecule (THF) or iodide, have been elucidated.
