title: Controlling regiochemistry in Negishi carboaluminations. Fine tuning the ligand on zirconium.
abstract: The species on the zirconocene catalyst is changed from two Cp's to the Brintzinger ligand and catalytic amounts of MAO are used to usually effect a >99% regiocontrol of Negishi carboaluminations of 1-alkynes in toluene.
