The transition metals chromium, tungsten, and molybdenum commonly form complexes with benzene rings. The metal forms a bond with the six electrons in the ? system of the benzene ring. In this experiment two of such molybdenum complexes are synthesized: (mesitylene)tricarbonylmolybdenum and (chlorobenzene)tricarbonylmolybdenum shown in figure 1.

Figure 1. (mesitylene)tricarbonylmolybdenum (a) and (chlorobenzene)tricarbonylmolybdenum (b)

Two common methods for the synthesis of these tricarbonylmolybdenum complexes are used in the experiment. Method 1 is used to synthesize (mesitylene)tricarbonylmolybdenum and method 2 is used to make (chlorobenzene)tricarbonylmolybdenum. Method 1, the direct method, involves the heating of hexacarbonylmolybdenum with excess mesitylene. This method requires high reaction temperatures which can result in the decompo
