Abstract

Reaction of [(CO) 4Fe (CO2R)]–(1)(R= Me or But) 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.
