应用：因其在空气和湿气环境中具有高稳定性,双联频哪醇硼酸酯(B2pin2)是有机合成中最常用的二硼烷试剂。 用于构造四甲基吡咯烷硝基氧支架，以通过 Suzuki 偶联反应合成顺磁性杂环化合物。用于铂催化乙炔和烯烃顺式邻二硼化反应的试剂;也可用于钯催化芳香烃的硼化反应。钯催化 1.6-烯炔环化生成高烯丙基烷基硼酸酯的新型反应的底物。
Application：Due to its high stability in air and humid environments, bis(pinacolato)diboron (B2pin2) is the most commonly used diborane reagent in organic synthesis. Used to construct a tetramethylpyrrolidine nitrooxide scaffold for synthesizing paramagnetic heterocyclic compounds through Suzuki coupling reaction. Reagent for platinum catalyzed cis orthoboration of acetylene and olefins; It can also be used for palladium catalyzed boronization reactions of aromatic hydrocarbons. A novel substrate for palladium catalyzed cyclization of 1.6-alkyne to produce high allyl alkyl borate esters.
