Bis(triphenylphosphine)palladium(II) Dichloride
Bis(triphenylphosphine)palladium(II) Dichloride (CAS: 13965-03-2) is an air-stable palladium(II) phosphine complex used as a homogeneous catalyst precursor in modern cross-coupling chemistry.
It is easy to handle compared with many palladium(0) sources and is reduced in situ to the active catalytic species, which makes it a practical choice for both laboratory and production-scale work.
The complex is commonly specified for Suzuki, Sonogashira, Stille and Heck reactions in pharmaceutical, agrochemical and electronic-material synthesis, where reliable palladium content and low impurity levels matter.
The complex is a solid that is stable in air for handling, but is best stored in a cool, dry place in sealed containers. Typical specifications include palladium content, appearance and residual solvent, which help process chemists control catalyst loading and cost.
• Cross-coupling catalysis: efficient precursor for Suzuki, Sonogashira, Stille, Heck and Negishi couplings that form carbon-carbon bonds. It is frequently selected when a stable Pd(II) source is preferred over air-sensitive Pd(0) reagents.
• Pharmaceutical and fine-chemical synthesis: supports construction of aryl and alkynyl building blocks for active ingredients and intermediates. Its reliable performance helps shorten route-scouting time and supports reproducible scale-up.
• Electronic and OLED materials: used to assemble conjugated organic molecules and polymers for semiconductor and display applications. Conjugated products from these couplings are key components of light-emitting and charge-transport layers.
• Carbonylation and C-N coupling: applied in carbonylation, amination and related palladium-catalysed transformations where a phosphine-stabilised palladium species is required.
