Controlling Regiochemistry in Negishi Carboaluminations. Fine Tuning the Ligand on Zirconium
摘要:
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.
