  secondary C-H bonds, which are adjacent to an oxygen or nitrogen atom on one side, and benzylic or adjacent to a carbonyl group on the other side. A variety of valuable fused heterocycles were obtained from easily accessible ortho-bromophenol and aniline precursors. The second C-H bond cleavage was successfully replaced with carbonyl insertion to generate other types of C(sp3 )-C(sp3 ) bonds.

  通过从三取代的芳基溴化物进行的1,4-Pd转移，可以使两个C（sp3）-H键形成一个C（sp3）-C（sp3）键进行分子内偶联。与大多数C（sp3）-C（sp3）交叉脱氢偶联相反，该反应在氧化还原中性条件下进行，其中C-Br键充当内部氧化剂。此外，它允许两个中等酸性的伯或仲CH键之间的偶联，其在一侧与氧或氮原子相邻，而在另一侧为苄基或与羰基相邻。从易于获得的邻溴苯酚和苯胺前体中获得了各种有价值的稠合杂环。第二个CH键裂解成功地被羰基插入取代，以生成其他类型的C（sp3）-C（sp3）键。
