  Benzylic C–H activation and C–O bond formation via aryl to benzylic 1,4-palladium migrations

  摘要：

  A procedure for benzylic C-H activation has been developed using a palladium 1,4-aryl to benzylic migration as a key step. Carboxylates and phenoxides readily trap the resulting benzylic palladium intermediates obtained from palladium 'through space' migration. Aryl bromides and iodides have been successfully employed in this reaction, furnishing moderate to good yields. The mechanism of this reaction has been studied by deuterium-labeling experiments, which suggest that the migration of palladium from an aryl to a benzylic position occurs reversibly. The reaction conditions developed for the migration process also oxidize the neighboring benzylic alcohols to the corresponding aldehydes and ketones. (C) 2008 Elsevier Ltd. All rights reserved.

  to effect the reductive carbonylation of aryl halides in moderate to good yield. In this reaction, water is the hydride source, and CO serves both as the carbonyl source and the terminal reductant through the water–gas shift reaction. The catalytic generation of the Rh hydride allows for the selective formation of highly hindered aryl aldehydes that are inaccessible through previously reported reductive

  开发了一种新型的 Pd/Rh 双金属协同催化工艺，可以以中等至良好的产率实现芳基卤化物的还原羰基化。在该反应中，水是氢化物源，CO在水煤气变换反应中既作为羰基源又作为终端还原剂。 Rh 氢化物的催化生成允许选择性形成高度受阻的芳基醛，这是通过先前报道的还原羰基化方案无法获得的。此外，使用D 2 O作为具有成本效益的氘源，可以高效、选择性地合成具有氘代甲酰基的醛，而无需预先合成醛。
