СО cat. H + NH2CH3 + H2CO2C CO2CH3 CO CHE Cocaine has been prepared by a sequence beginning with a Mannich reaction between dimethyl acetonedicarboxylate, methylamine, and butanedial. The mechanism involves the following steps: 1. Following initial protonation of the carbonyl oxygen, nucleophilic attack by the amine forms carbinolamine 1; 2. Proton transfer and elimination of water forms iminium ion 2; he enol form of the dicarboxylate ester attacks the iminium ion to form adduct 3; 4. Adduct 3 tautomerizes...

Can you help me identify reagent (i), Compound 8 and
Compound 12 in the reaction scheme?
You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
The lab data for Compound 8 and 12 is as
follows:
You can use any...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
