Both products are the same catalyst, but in different forms. Product 669032 is a powder, while 685143 is the catalyst in tablet form. A specific amount of catalyst (2μmol for 685143) is impregnated into an inert tablet matrix as a time-saving alternative to weighing out the catalyst. More information on the ChemDose tablets is found at:

Pd-N-heterocyclic carbene (NHC)-catalyzed Buchwald-Hartwig amination protocols mediated by Pd-PEPPSI precatalysts is described. These protocols provide access to a range of hindered and functionalized drug-like aryl amines in high yield with both electron-deficient and electron-rich aryl- and heteroaryl chlorides and bromides.
