developed. By taking advantage of in-situ generated alkoxide ligand arising from the carbonate substrate, the reaction proceeds smoothly even under external base-free conditions. The resulting benzyl silane moiety can undergo the post functionalizations to deliver the more complex diarylmethane derivatives. Additionally, the related base-free allylic silylation reaction is also demonstrated.
已开发出钯催化的二芳基甲基碳酸酯与甲硅烷基硼烷的苄基甲硅烷基化反应。通过利用碳酸盐底物原位生成的醇盐配体,即使在外部无碱条件下,反应也能顺利进行。所得苄基硅烷部分可以进行后官能化以提供更复杂的二芳基甲烷衍生物。此外,还展示了相关的无碱烯丙基甲硅烷基化反应。
