Mechanism of the reduction of 4-tert-butylcyclohexanone. The Meerwein-Pondorff-Verley MPV reaction using aluminum isopropoxide in the presence of isopropyl alcohol provides a reversible reduction of ketones and aldehydes3 In the MPV. In sharp contrast MPV reduction of 4-tert-butylcyclohexanone yielded 95 conversion in 4 days similar to those reported for Zr-TUD-1.

Mechanism for the reduction of 4-tert-butylcyclohexanone with sodium borohydride in. 4-tert-Butylcyclohexanone is dissolved in cold ethanol. Discussion The percent yield was around 76 percent so the reaction can be considered successful.

The trans product is the product that is most dominant in this situation because it is a more stable conformation and easier to take on. Using the starting material 4-t-butylcyclohexanone and the. 3 4 Eliel and Ro 5 obtained cis-rich 4-tert-butylcyclohexanol by the reduction of 4-tert-butylcyclohexanone with hydrogen on platinum oxide in glacial acetic acid containing some hydrogen chloride.

In the experiment 4 the reduction reaction is what is being performed. Show electron flow for ALL steps. The thermodynamically favored product was formed because sodium borohydride is not a sterically hindered reducing agent and is therefore able to attack the 4- tert -butylcyclohexanone from the top face of the molecule despite the presence of the large.

The mechanism involved Lewis work Al species of strong Lewis acidity and catalyzed the reduction acid sites described as Al species partially attached to the of cinnamaldehyde into isopropyl-cinnamyl ether thus suggesting lattice 8. Significantly less basic and the acid-base reaction is much slower. After reduction and before liquid-liquid extraction we added distilled water and 3M HCl to the solution until H gas ceased production.
