palladium catalyzed borylation of a Boc protected aminobromoquinoline compound with bis(pinacolato)diboron yielded a biaryl compound, resulting from cross coupling, as the major product, instead of the intended boronate, even though no strong base was used. Such results indicate that under certain conditions and with certain substrates, cross coupling can be a major problem during borylation, leading to unintended
即使没有使用强碱,Boc 保护的氨基溴喹啉化合物与双(频哪醇)二硼的钯催化硼基化产生了由交叉偶联产生的联芳基化合物作为主要产物,而不是预期的硼酸酯。这些结果表明,在某些条件下和某些底物下,交叉耦合可能是硼化过程中的一个主要问题,导致意想不到的后果。
