Homework Help: Grignard Synthesis - need help naming product

  1. Aug 1, 2007 #1
    1. The problem statement, all variables and given/known data
    What is the solid that forms during the addition of phenyl magnesium bromide to methyl benzoate (step before triphenylmethanol)?

    2. Relevant equations
    See below.

    3. The attempt at a solution
    I know the structure of the product, but I don't know exactly how to name it. The product has a carbon bonded to three phenyls, and the fourth bond is to OMgBr.

    There aren't three phenyls in the product. You are adding one phenyl group to methylbenzoate, which has only one phenyl group itself. If you are adding 2 equivalents of the grignard, you are correct but the question specifically asks for the product "...(step before triphenylmethanol)".
