WebFigure 1. General reaction mechanism for the Grignard reaction. The mechanism is depicted in Figure 1. As pictured previously, the first part of the reaction is the formation of the Grignard reagent. The first step is a free radical coupling of the Mg to the halide X leaving the alkyl .. Then, the radical, R alkyl radical and the Mg-X combine ... WebB. Triphenylmethanol Synthesis: While the Grignard reagent is being prepared, make the benzophenone solution. 1. Calculate the mass of 1.5 mmoles of benzophenone (MW = 182.220 mg/mmole) to the nearest mg. Record the calculation. Tare the capped dry 3 ml conical vial that was previously used for the bromobenzene.
