Several bis-or tris (pyrazol-1-yl) triazine derivatives have been synthesized and used as ligands in the synthesis of cationic allyl-or bis (pentafluorophenyl) palladium complexes. In bis-palladated complexes hydrolysis of one pyrazole group is seen. The allyl palladium complexes show fluxional behavior, implying apparent π-allyl rotation and metallotropic shifts. Different activation energies, related to the strength of the Pd-N bond to be broken, ...
