Explanation:
Lindlar’s Catalyst For The Partial Reduction Of Alkynes To cis-Alkenes
In a blatant plug for the Reagent Guide, each Friday I profile a different reagent that is commonly encountered in Org 1/ Org 2. Version 1.2 just got released, with a host of corrections and a new page index.
One thing that’s useful to keep in mind as you learn about reagents is that there are some reagents that will only descend (or ascend) one rung of the oxidation ladder at a time. Last week, it was sodium borohydride, which reduces aldehydes and ketones but doesn’t touch esters. This week, it’s Lindlar’s catalyst, which reduces alkynes, and stops at the alkene.
What it’s used for: the Lindlar catalyst is a “poisoned” metal catalyst that performs hydrogenations of alkynes in the presence of hydrogen gas (H2). By “poisoned”
