(10 pts) Give the product (s) of the following reaction and propose a mechanism. 4. H2NNH2, H (cat.)
1. Propose a mechanism: Starting material: butyraldehyde Solvent: water Reagent: Potassium Hydroxide(KOH) Final product: 2-ethyl-3-hydroxy-hexanal 2. Propose a mechanism: Starting material: Methyl Propionate Solvent: water Reagent: HCl Final product: propionic acid
2. What is the product of the following reaction? HPTS NaNH (2 equiv.) Cl C
QUESTION 4 [1,2- versus 1,4-Addition Reactions] 4.1 Propose a detailed mechanism for the reaction of 2-butenal with ethynylmagnesium bromide in dry THF followed by quenching with dilute aqueous acid. (5) 4.2 Propose a plausible mechanism for the reaction of 1,3-diphenyl-2-propen-1- one with potassium cyanide in ethanol followed by aqueous work-up. 1 (5) 4.3 Predict and draw the structure of the product of the reaction of 2-methyl-1,3- cyclohexanedione with methyl vinyl ketone (3-buten-2-one) in methanol in the presence of potassium hydroxide....
4. (a) A WileyPlus problem from the (now defunct) Ch. 21 assignment I used to give asked about the product formed from the aromatic nitrile below upon reaction with amide. Their product was actually quite different than mine... That said, both have plausible mechanisms to support their formation. Propose two different mechanisms to explain the formation of the two different products (don't bother drawing the mechanism of the acidic workup that's Ch. 16). (9 points) WP answer 2 equiv KNH2...
(2 pts) Show the complete mechanism using curved arrow formalism for the reaction of 4-ethyl-1-cyclohexanecarboxaldehyde treated with ethylene glycol in acid. Provide the 1H and 13C NMR data for the product formed in Question #1. Report the 1H NMR data in the sequence: chemical shift, integration, multiplicity (e.g. d 1.0, 3H, triplet). Be sure to clearly label which proton and carbon you are reporting.
