Sequential formation of distant bonds in organic molecules was achieved for the palladium‐catalyzed hydrosilylation/cyclization of various 1,n‐dienes by chain walking of the metal catalyst. The reaction was applicable to various 1,n‐dienes, including a 1,13‐diene, to form a cyclopentane ring as well as a carbon–silicon bond at a remote site. The use of “nondissociative” chain walking provides a fascinating
通过金属催化剂的链行走,钯催化的各种1,n-二烯的氢化硅烷化/环化反应实现了有机分子中远键的顺序形成。该反应适用于各种1,n-二烯,包括1,13-二烯,可在远端形成环戊烷环以及碳-硅键。“非解离”链走的使用为有机合成提供了一种引人入胜的策略,通过有效地将反应中心从较远位置移开,可以在催化循环内以特定顺序功能化有机分子的遥远部分。
