Selective hydrogenations
« on: April 22, 2015, 03:34:10 AM »
Does anyone know of a method to selectively hydrogenate a cis 1,2 disubstituted double bond in the presence of a 1,1 disubstituted double bond?

Probably need more information.  What do you have coming off the alkenes?
When in doubt, avoid the Stille coupling.

There are no heteroatoms near either of them, and both are in rings. The one I want to reduce is internal and the one I need intact is exocyclic.
