# What is the Mechanism of hydrogenation of alkenes by Wilkinson's catalyst?

I've learnt that the Wilkinson's catalyst $$[\ce{Rh(PPh3)3}]$$ is used for hydrogenation of alkenes into alkanes. But I'm curious to know the mechanism. Could someone help me?

• Yes, I tried looking at the wiki page.. but I didn't quite understand it😅 – The Jade Emperor Jan 19 at 4:00
• Catalytic hydrogenation or any catalytic mechanism of any transition metal is normally not taught in high school as it is a more difficult topic to study. But the fact is that the mechanism remains same. There is no easy way to interpret. What happens is what you have to study. So i would suggest to go through mechanism of basic catalysts and then go through transition metal as catalyst. – Nilay Ghosh Jan 19 at 4:06
• You can't draw arrow pushing mechanisms exactly for some of the steps, but as with any other reaction mechanism, you want to know the basic steps. These are: oxidative addition (specifically, concerted), $\beta$-migratory insertion, and reductive elimination. There's also a regular ligation in the middle, which is just a Lewis acid/Lewis base interaction. – Zhe Jan 19 at 13:08
