Useful Palladium Catalyst

Sterically bulky [1,1'-bis(di-tert-butylphosphino)ferrocene]palladium(II) dichloride (1) is a complex of an electron-rich bidentate phosphine ligand and palladium(II). The large bite angle of 1 imparts high catalytic activity to the catalyst. In the Suzuki-Miyaura reaction, for example, even unactivated aryl chlorides or very sterically hindered substrates undergo reaction to give the corresponding coupling products in high yields.¹⁾ In addition, its high stability in air is one of the features of this catalyst, which increases its utility in a number of fields.
