General description

Pd(COD)(DQ) is a rare example of a robust, air-stable, phosphine free 18 electron Pd(0) complex. The complex easily undergoes facile ligand exchange with a range of ancilliary ligands to give useful palladium compounds suitable for a range of catalytic transformations.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Zero-valent palladium species are active catalytic species in a range of useful catalytic reactions, including C-C coupling, C-N coupling, allylic substituion and alkene funcitonilizaiton reactions.

Features and Benefits

Pd(COD)(DQ) offers:

  • High thermal and air stability.
  • Benign ligands that do not interfere in catalytic reactions once ligand exchange has occurred.
  • Good solution stability.

Storage Class

11 - Combustible Solids

We have discovered that the dba ligand in the commonly used Pd2(dba)3·CHCl3 cross-coupling pre-catalyst is susceptible to bis-arylation when used in the presence of aryl iodides. The in situ formed dbaAr2 ligands result in Pd-species with altered catalytic activity. In
