Compounds are provided that act as potent antagonists of the CCR1 receptor, and which have been further confirmed in animal testing for inflammation, one of the hallmark disease states for CCR1. The compounds are generally aryl piperazine derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR1-mediated diseases, and as controls in assays for the identification of competitive CCR1 antagonists.

and the cationic allyl complex 8 were prepared and characterized by NMR spectroscopy as well as crystal structure analyses. The carbonyl group of the carboxylic ester moiety does not form a chelate with the metal atom. The activation enthalpy of a π–σ–π conversion could be determined to be 14.6 kcal mol−1 based on the dynamic NMR spectroscopy of the allylpalladium complex 8.
