The carbonyl‐alkyne metathesis reaction is a powerful method for the synthesis of α,β‐unsaturated carbonyls. We now report on the development of a halogen‐bond catalyzed protocol for both the intra‐ and intermolecular reaction. Our studies revealed that methanol is a highly efficient solvent ...

A three step synthesis from the alkyne product from a starting alcohol using reactions that are typically covered in the first few weeks of class. Practice is the only way to learn these tricks and the more reactions you know, the easier it will be to find shortcuts to faster synthesis sch...
Now let’s look at some Hydration Reactions. Hydration of Terminal Alkyne produces methyl ketones Just as described in Figure 7 the π electrons will attack a proton, forming a carbocation, which then gets attacked by the nucleophilic water molecules. After deprotination, we generate an enol, ...
There are thousands of different reactions that can occur in organic chemistry. Understanding the mechanisms behind the reaction will allow a better understanding of what products will form or what reaction needs to occur for a specific product to be formed. It also often helps understand the ...
