Palladium-catalyzed ortho-C(sp2)[sbnd]H bromination of benzaldehydes via a monodentate transient directing group strategy

A facile and efficient monodentate transient directing group strategy was developed to enable the palladium-catalyzed ortho-C(sp2)[sbnd]H bromination of benzaldehydes. A broad scope of benzaldehydes were transformed into the desired products by employing 2-amino-5-chlorobenzotrifluoride as a monodentate transient directing group, demonstrating good functional group tolerance. Mild reaction conditions and no requirement for a silver salt are also features of this strategy.

A Bio-inspired Approach for Chromophore Communication: Ligand-to-Ligand and Host-to-Guest Energy Transfer in Hybrid Crystalline Scaffolds

Efficient multiple-chromophore coupling in a crystalline metal-organic scaffold was achieved by mimicking a protein system possessing 100 % energy-transfer (ET) efficiency between a green fluorescent protein variant and cytochrome b562. The two

Selective ortho -bromination of substituted benzaldoximes using Pd-catalyzed C-H activation: Application to the synthesis of substituted 2-bromobenzaldehydes

Substituted 2-bromobenzaldehydes were synthesized from benzaldehydes using a three-step sequence involving a selective palladium-catalyzed ortho-bromination as the key step. O-Methyloxime serves as a directing group in this reaction. A rapid deprotection of substituted 2-bromobenzaldoximes afforded substituted 2-bromobenzaldehydes with good overall yields.
