Synthesis and Migratory-Insertion Reactivity of CpMo(CO)3(CH3): Small-Scale Organometallic Preparations Utilizing Modern Glove-Box Techniques
This laboratory experiment spans three weeks and introduces advanced undergraduates to modern small-scale synthesis techniques involving an inert-atmosphere glove box. The robust syntheses transform [CpMo(CO3]2 into the methylated CpMo(CO)3(CH3) and examine the phosphine-induced migratory insertion to form various Cp-supported Mo(II) acetyl complexes. At each step in the synthesis, a combination of IR and multinuclear (1H, 13C, and 31P) NMR spectroscopies allow students to assess the purity of their products and
