We report the synthesis of 2-(anthracen-9-yl)-1H-inden-3-yl dicyclohexylphosphine and its use in palladium-catalyzed borylation/Suzuki-Miyauracross-coupling reaction to prepare a variety of symmetrical and unsymmetrical biaryl compounds in excellent yield.

Heteroarylzirconocene halides were prepared via the oxidative addition of heteroarylhalides to the Negishi reagent ‘Cp2ZrBu2’. The palladium-catalyzed cross-coupling of the in situ generated organozirconium reagents with functionalized aryl and heteroarylhalides proceeded smoothly in the presence of CuCl to produce the cross-coupling products in high yields.

electron-rich aromatic amines, aliphatic amines, and phenacyl bromide derivatives proceeded the present transformation with marginally superior reactivity in comparison to electron-deficient aromatic amines and phenacyl bromide derivatives. Moreover, several control experiments, in situ isolation of secondary amine and imine as key intermediates, and 18O-labeling experiments provide complete insight into the mechanism
