We describe transfer carbonylation reactions of 2‐bromoarenes that contain a carbon‐nucleophile using aldehydes as a substitute for CO, leading to the formation of indanone derivatives. The transformation proceeds efficiently under Rh^I/Pd⁰‐hybrid catalytic conditions consisting of two discrete transition metals, rhodium and palladium, which catalyze the decarbonylation of aldehydes and the subsequent carbonylation of bromoarenes using the resulting carbonyl moiety, respectively. The majority of the abstracted CO is transferred directly to the product via a CO‐relay process from rhodium to palladium.

铑和钯之间通过CO中继的具有C-亲核试剂的卤代芳烃的无CO气体分子内环羰基化反应

我们描述了使用醛代替CO的含碳亲核试剂的2-溴代芳烃的转移羰基化反应，从而导致茚满酮衍生物的形成。在由两种离散过渡金属铑和钯组成的Rh ^I / Pd ^0混合催化条件下，该转化有效地进行，这两种催化金属分别催化醛的脱羰作用和随后使用所得羰基部分进行的溴代芳烃的羰基化。大部分提取的CO均通过从铑到钯的CO中继过程直接转移到产品中。
