The coordination chemistry and reactivity of group 13 metal(I) heterocycles

This article summarizes the synthetic strategies that have been used to prepare anionic five-membered and neutral six-membered heterocycles containing a group 13 metal in the +1 oxidation state. In addition, a survey of the coordination chemistry and reactivity of these species is described, drawing comparisons with the well known N-heterocyclic carbene class of ligand where possible. Computational studies of the free heterocycles and their complexes are also reviewed.
