The Grignard Reaction – Unraveling a Chemical Puzzle

WebTriphenylmethanol can be formed by using a Grignard reagent. In order for this to occur, a Grignard reagent must first be made. 2 This is done by forming phenylmagnesium bromide from bromobenzene, an organic halide, and magnesium. ... Figure 1: Figure one shows the mechanism for the formation of the Grignard reagent from magnesium and bromobenzene. WebThe Grignard reaction usually takes place in ethereal solvents, the final alcohol product being obtained by hydrolysis.
