group compatibility renders silylzinc reagents desirable; however, their development is hindered by their synthesis using pyrophoric silyllithium and dissolved lithium salts. Our solid Me3SiZnI circumvents these limitations and herein, we demonstrate its significance in the cross-coupling of aryl and alkyl bromides.
使用乙硅烷和甲硅烷基硼烷的过渡金属催化合成有机硅烷克服了传统氢化硅烷化的局限性。虽然乙硅烷需要特殊条件,但甲硅烷基硼烷尚未开发为 TMS 来源。官能团相容性使得硅锌试剂成为理想的选择;然而,它们的发展受到使用自燃硅基锂和溶解的锂盐合成的阻碍。我们的固体 Me3SiZnI 规避了这些限制,在此,我们证明了其在芳基溴和烷基溴交叉偶联中的重要性。
