A method of performing a chemical reaction includes reacting a compound selected from the group consisting of an organohalide and an organo-pseudohalide, and a protected organoboronic acid represented by formula (I) in a reaction mixture:
R
1
—B-T (I);
where R
1
represents an organic group, T represents a conformationally rigid protecting group, and B represents boron having sp
3
hybridization. When unprotected, the corresponding organoboronic acid is unstable by the boronic acid neat stability test. The reaction mixture further includes a base having a pK
B
of at least 1 and a palladium catalyst. The method further includes forming a cross-coupled product in the reaction mixture.
一种化学反应的方法包括在反应混合物中反应从有机卤化物和有机伪卤化物中选择的化合物,以及由公式(I)表示的受保护的有机硼酸:R1—B-T (I);其中,R1表示有机基团,T表示构象刚性保护基团,B表示具有sp3杂化的硼。当未受保护时,相应的有机硼酸在硼酸稳定性测试中不稳定。反应混合物还包括具有至少1的pKB值和钯催化剂的碱。该方法还包括在反应混合物中形成交叉偶联产物。
