# What is the product of reaction between 2‐cyclobutyl‐2‐isopropyl‐1,3‐dioxane and hydrogen with Raney nickel?

I have 2‐cyclobutyl‐2‐isopropyl‐1,3‐dioxane (alcohol protection) and I have to react it with $$\ce{H2}$$ and Raney nickel, but I don't know what the product would be.

I have seen a similar reaction that uses sulfur atoms instead of the oxygens and at the end the entire protection is removed and leaves two $$\ce{H}$$ atoms in the end. I tried doing that, but my professor told me that I got it wrong. I'm thinking that there wouldn't be a reaction.

• Raney nickel desulfurization applies to sulfur not oxygen deoxygenation. It is possible your professor is expecting reduction of the cyclobutane ring. – user55119 Apr 3 at 16:37
• @user55119 that would have been my gut shot too – Beerhunter Apr 4 at 9:08
