Radical chain ligand substitution of [(η5-RC5H4)2Fe2(CO)4] with isocyanides induced by Et3B
Abstract
Reaction of [(η5-RC5H4)2Fe2(CO)4] with isocyanides in the presence of a catalytic amount of triethylborane results in the selective monosubstitution of the CO ligand with the isocyanide; a radical chain process is proposed for the reaction.
