    • Boronic esters and boronic acids are synthesized at ambient temperature in an ethereal solvent by the reaction of Grignard reagents with a boron-containing substrate. The boron-containing substrate may be a boronic ester such as pinacolborane, neopentylglycolborane, or a dialkylaminoborane compound such as diisopropylaminoborane. The Grignard reagents may be pre-formed or generated from an alkyl, alkenyl, aryl, arylalkyl, heteroaryl, vinyl, or allyl halide compound and Mg0. When the boron-containing substrate is a boronic ester, the reactions generally proceed at room temperature without added base in about 1 to 3 hours to form a boronic ester compound. When the boron-containing substrate is a dialkylaminoborane compound, the reactions generally proceed to completion at 0° C. in about 1 hour to form a boronic acid compound.
    • 通过Grignard试剂与含硼底物的反应,在环境温度下在醚溶剂中合成硼酸酯和硼酸。 含硼底物可以是硼酸酯,例如频哪醇硼烷,新戊基乙二醇硼烷,或二异丙基氨基硼烷等二烷基氨基硼烷化合物。 格氏试剂可以由烷基,烯基,芳基,芳基烷基,杂芳基,乙烯基或烯丙基卤化合物和MgO预先形成或生成。 当含硼底物是硼酸酯时,反应通常在室温下进行,而不在约1至3小时内加入碱以形成硼酸酯化合物。 当含硼底物是二烷基氨基硼烷化合物时,反应通常在0℃下在约1小时内完成以形成硼酸化合物。
