Nucleophilic addition to tricarbonyliron(0) complexes of 1-aza-1,3-dienes and the production of pyrroles
Abstract
The synthesis of a number of novel tricarbonyl(1-aza-1,3-diene)iron(0) complexes and their reactions with methyl-lithium are described. Addition proceeds under mild conditions and, in general, occurs at a metal carbonyl ligand; this leads via an unprecedented reaction to the production of several novel pyrroles.
