Bis(pinacolato)diboron Use
Bis(pinacolato)diboron is a material to construct a tetramethylpyrrolidine nitroxide scaffold for the synthesis of paramagnetic heterocycles by Suzuki coupling. 
It is also a substrate in new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates.
