Platinum-Catalyzed Regio- and Stereoselective Diboration of Allenes by 1,8-Diaminonaphthalene-Protected Diboronic Acid (B <sub>2</sub> (dan) <sub>2</sub> )
We report a regio- and stereoselective diboration of the terminal C═C bond of allenes by B<sub>2</sub>(dan)<sub>2</sub> (dan = naphthalene-1,8-diaminato) in the presence of a Pt catalyst. This reaction is applicable to a broad range of substrates, including 1-arylallenes and 1,1-disubstituted allenes. The two boryl groups in the product exhibit distinct reactivities, enabling chemoselective transformations.
