Question

Predict the products formed when cyclohexanone reacts 
with the following reagents.
(i) hydrazine, then hot, fused KOH

Accepted Answer

All right. Hi everyone. So for this question we must draw the products expected from the reaction between cyclo Penton on and hydrazine followed by treatment with hot fused um potassium hydroxide. So, before we begin, let's notice here that in the text of the question, we are reacting a ketone, cyclo Penton in with hydrogen followed by hot K O. H. As a separate step. So recall that these conditions are going to be indicative of the so called wolf Kissner reduction. Right? So in a wolf Kissner reduction, an alcohol or a ketone is going to undergo de oxygenation. Because when we react are all the hydro ketone with um hydrazine, then we are going to have a hydro zone intermediate. Right? So that oxygen in our Aldo hydro ketone is going to be replaced by the hydro um hydrazine. And this is going to be hydrazine in the beginning, followed by our hydro zone intermediate plus water. Right, so this hydro zone intermediate and water are going to react with K. O. H in the presence of heat to generate an ocular carbon instead. Right, there will be no oxygen present. And that is what we mean when you refer to a de oxygenation. Right? So if we go ahead and we follow the same pattern that we discussed with our cycle Penton on, we're going to have a five carbon ring with a car bottle attached. And when we react this, right, our cyclops fentaNYL with hydrogen first of all for N two H four, followed by um hot fused K. O. H. Then we're going to get rid of our carbonnel in our cycle, a Penta known, and we are simply going to have a CH two group encyclopedia entertain instead. So this is going to be our de oxygenation product, and this is going to be your final answer. So with that being said, thank you for watching and I hope you found this helpful.
