Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown.  Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.)  (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
