Bis(pinacolato)diboron is used to construct a tetramethylpyrrolidine nitroxide scaffold for the synthesis of paramagnetic heterocycles by Suzuki coupling. It is also a substrate used in new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates.用于乙炔和石蜡（铂催化）的顺式-连位硼化试剂； 钯催化的芳香族化合物的硼化。 钯催化的1,6-烯炔的环化生成高烯烷基硼酸盐（homoallylic alkylboronates）反应中的底物。 Bis(pinacolato)diboron is used to construct a tetramethylpyrrolidine nitroxide scaffold for the synthesis of paramagnetic heterocycles by Suzuki coupling. It is also a substrate used in new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates. A reagent used for the cis-vicinal diborylation of acetylenes and olefins with Pt catalysis; borylation of aromatics by Pd catalysis
