The mechanism for imine formation can be simplified into five common steps. Arrange these steps in...
oleh Secondary amines add to aldehydes and ketones to give enamines. Enamines are formed in a reversible, acid-catalyzed process that begins with nucleophilic addition of the secondary amine to the carbonyl group, followed by transfer of the proton to yield a neutral carbinolamine. Protonation of the hydroxyl group converts it into a good leaving group, however there is no hydrogen left on the nitrogen to be lost to form a neutral imine product. Instead, a proton is lost from the...
Identify the products of the following reactions and propose a
mechanism for its formation. Please explain each step i.e.
protonation, deprotonation, loss of leaving group, or nucleophilic
attack and describe what kind of reactions they are. Include BOTH
major and minor products. Thank you in advance.

Determine the correct order of steps that will occur for the possible reaction shown below. To enter your answer use the numbers that are adjacent to the correct descriptions in the correct order. For example, if you felt that 1, followed by 2 and then 3 reflects the correct ordering of reaction steps, then you would enter: 1, 2, 3 for your answer. Do so even if the reaction sequence includes two distinct steps (with two different conditions/reagents)....

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...

Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...
