Synthesis of Molecular Phenylcalcium Derivatives: Application to the Formation of Biaryls
Résumé
Hydrocarbon-soluble beta-diketiminato phenylcalcium derivatives, which display various modes of Ca-mu(2)-Ph-Ca bridging, are accessible from reactions of Ph2Hg and [(BDI)CaH](2). Although the resultant compounds are inert toward the C-H bonds of benzene, they yield selective and uncatalyzed biaryl formation when reacted with readily available aryl bromides.
