5
What is the product of the following reaction?
11.2 What is the product of the following reaction? The Grignard reagent (nucleophile; R-MgBr or “C”) forms first which then reacts with a proton from H2O (electrophile). This is formally a reduction. THF is only a solvent. Bruice: Organic Chemistry, © 2011 Pearson Education, Inc.
