Synthesis of Alkyl(alkoxycarbonyl)tetracarbonyliron Complexes : the First Evidence of their Relevance to the Catalytic Cycle in the Carbonylation of Organic Halides induced by Pentacarbonyliron

Article abstract of DOI:10.1039/c39880000929

Reaction of <(CO)4Fe(CO2R)>(1-) (1) (R = Me or Bu^t) with BrCH2CO2Me produces stable complexes <(CO)4Fe(CH2CO2Me)(CO2R)> (3) which thermally decompose to yield Fe(CO)5 and malonic esters under a CO atmosphere; these reactions provide the first demonstration of possible key steps in the catalytic cycle of the carbonylation of reactive halides into esters with Fe(CO)5 and an alkoxide anion.
