The first iron-catalysed aluminium-variant Negishi coupling: critical effect of co-existing salts on the dynamic equilibrium of arylaluminium species and their reactivity.

The first example of an iron-catalysed Negishi coupling between arylaluminium reagents and alkyl halides illustrates that the co-existing salts highly influence the dynamic equilibrium of the organoaluminium species, and have a critical effect on the reactivity and selectivity of the coupling reaction.
