Anhydrous: The substance in use contains no water. This is primarily important in reactions that cannot occur in the presence of water, such as using the Grignard reagent.


Degasification: The process of removing dissolved gasses from solution. This is done because molecules in solution may be air-sensitive.


Molecule 14: Starting material used in our reaction


Molecule 15: The product formed after the Pauson-Khand synthesis step in our reaction.



Reduced Pressure: It is easier for liquids such as solvents to boil off at reduced pressure, thereby removing impurities.


Rh[Cl(CO)2]2: The metal catalyst used in the Pauson-Khand reaction in our journal.



Sonication: Applying sound energy to excite particles in a sample, helping to speed dissolution.
