The palladium‐catalyzed silylation of aryl chlorides with silylsilatranes proceeds under activator‐free conditions; hence, wide functional group compatibility is displayed and boryl and siloxy groups are able to survive. Experimental and computational studies revealed that smooth transmetalation from the silylsilatrane to the arylpalladium chloride is facilitated by strong interaction between the Lewis
在无活化剂的条件下,钯催化的芳基氯与甲硅烷基硅烷基化的甲硅烷基化反应得以进行。因此,显示出广泛的官能团相容性,并且硼烷基和甲硅烷氧基能够存活。实验和计算研究表明,路易斯酸性硅与氯化物之间的强相互作用促进了从甲硅烷基硅石到芳基钯氯化物的平滑过渡金属化。
