  Exploiting coordination effects to prepare hydrocarbon-soluble alkyl organosodium reagents enables the efficient metalation of toluene derivatives under mild and stoichiometric conditions, and their facile conversion into 2-arylacetophenones. Through the isolation of key organometallic intermediates and their study in solution, new mechanistic insights have been gained into these sodium-mediated reactions
