Kinetics of reactions of bromine and iodine with some substituted dimanganese and dirhenium carbonyls

Abstract

Kinetic studies show that reactions of Br₂ and I₂ with several substituted dimanganese and dirhenium carbonyls occur via very rapid initial formation of intermediate adducts containing one or more halogen molecules; the dependence of the rates on the nature of the substituents is consistent with electrophilic attack by halogen at the extremity of the carbonyl ligands.
