General description

Palladium(II) acetate is an orange, brown, moderately water-soluble source of palladium. We provide palladium(II) acetate with a purity of 99.98% on a trace metals basis (< 250.0 ppm), making it ideal for a wide range of catalytic reactions.

Application

Palladium(II) acetate is used
  • As a precursor in the one-step solvothermal synthesis of carbon-supported PtPdCu nanoalloy catalysts, enabling the formation of uniform nanoparticles with enhanced catalytic activity and stability for fuel cell applications.
  • As a key catalyst in the Sonogashira–Hagihara cross-coupling reaction to synthesize microporous polymers, which are carbonized to produce high-performance porous carbon electrodes for supercapacitors and hydrogen evolution reactions.
  • As a precursor in the fabrication of metallic nanopatterns through focused ion beam-induced decomposition of spin-coated thin films, enabling the creation of conductive palladium nanostructures for applications in nanoelectronics and advanced lithography.

Features and Benefits

  • High palladium loading (46.2 - 48.6%) increases the availability of active sites for catalysis, leading to more efficient conversion of reactants into products as more palladium atoms are involved in the reaction.
  • Ultra-high purity (99.98% Trace Metals Basis) minimizes contamination, enhancing performance by reducing metal sintering, preventing irreversible reactions with catalytic species, and maintaining optimal electronic properties for better catalyst efficiency in palladium-sensitive applications.

A palladium-catalyzed dehydrogenative coupling between diarylamines and olefins has been discovered for the synthesis of substituted indoles. This intermolecular annulation approach incorporates readily available olefins for the first time and obviates the need of any additional directing group. An ortho palladation

A novel type of "X-shaped" two-dimensional electro-optic (EO) chromophore with extended conjugation has been synthesized and characterized. This chromophore is found to exhibit a remarkably blue-shifted optical maximum (357 nm in CH(2)Cl(2)) while maintaining a very large first hyperpolarizability (beta).
