Identifying the roles of amino acids, alcohols and 1,2-diamines as mediators in coupling of haloarenes to arenes.

Coupling of haloarenes to arenes has been facilitated by a diverse range of organic additives in the presence of KO(t)Bu or NaO(t)Bu since the first report in 2008. Very recently, we showed that the reactivity of some of these additives (e.g.
