SUMMARY

The solid formed during the addition of phenyl magnesium bromide to methyl benzoate is a magnesium alkoxide intermediate, specifically phenyl methyl benzoate. This product results from the nucleophilic attack of the Grignard reagent on the carbonyl carbon of methyl benzoate, leading to the formation of a tetrahedral intermediate before the eventual conversion to triphenylmethanol. The key reaction involves the addition of one equivalent of phenyl magnesium bromide, not two, as clarified in the discussion.

PREREQUISITES
  • Understanding of Grignard reagents and their reactivity
  • Knowledge of nucleophilic addition reactions
  • Familiarity with organic compound naming conventions
  • Basic principles of organic synthesis
NEXT STEPS
  • Study the mechanism of Grignard reactions in organic chemistry
  • Learn about the synthesis and properties of magnesium alkoxides
  • Explore the naming conventions for organic compounds, focusing on complex structures
  • Investigate the preparation of triphenylmethanol from Grignard reagents
USEFUL FOR

Chemistry students, organic chemists, and anyone involved in synthetic organic chemistry looking to deepen their understanding of Grignard reactions and product naming conventions.

Homework Statement


What is the solid that forms during the addition of phenyl magnesium bromide to methyl benzoate (step before triphenylmethanol)?

Homework Equations


See below.

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)".
