Catalytic transformations involving Pd s-alkyl or s-aryl intermediates are widely used in organic synthesis and offer attractive routes to many valuable products. However, the vast majority of these reactions proceed by Pd/Pd mechanisms. As a result, the diversity of structures/bonds that can be constructed is constrained by the limitations of this redox cycle. Recent studies have explored the ...

Aromatic fluorides are prevalent in both agrochemical and pharmaceutical agents. However, methods for their rapid and general preparation from widely available starting materials are limited. Traditional approaches such as the Balz-Schiemann and Halex reactions require harsh conditions that limit functional group tolerance and substrate scope. The use of transition metals to affect C-F bond for...

The detection of dissolved gas in transformer oil is vital importance to diagnose the early fault and monitor security stability power systems. In this work, distinct Pd/C, Pd/C-R Pd/NC were synthesized evaluated. XRD XPS characterizations show that both Pd0 PdII are presented over surface carbon host for while poor gas-sensitive properties H2-reduced sample. High content cationic species by ni...

The site-selective functionalization of C−H bonds within a complex molecule remains challenging task capital synthetic importance. Herein, an unprecedented Pd-catalyzed C(sp2)−H alkoxycarbonylation phenylalanine derivatives and other amines featuring picolinamide as the directing group (DG) is reported. This oxidative coupling distinguished by its scalability, operational simplicity, avoids use...
