    • A direct transformation through a single activated complex (for instance a species with the Au and Pd centers bridged by the two exchanging groups) would yield a rate law independent of [L].

    • note
    • Other observations further support the proposed mechanism. For example, isomerizations on similar Pt(II) complexes are much slower than for Pd, in agreement with the different behavior of these two metals in associative substitutions (see ref 20). This and other results will be reported in a forthcoming paper.
