AARAV Fragrances and Flavors Interview Questions, Process, and Tips

Vilsmeier-Haack reaction is a chemical reaction used to form aldehydes and ketones from aromatic compounds.

• Involves the reaction of an aromatic compound with DMF and POCl3

• Produces an intermediate that can be hydrolyzed to form the desired aldehyde or ketone

• Can also be used to form imines and amides

• Named after the chemists who discovered it: Albrecht Vilsmeier and Rudolf Haack

I perform a variety of name reactions depending on the project requirements.

• I have experience with common name reactions such as Grignard reaction, Friedel-Crafts reaction, and Wittig reaction.

• I also have experience with more specialized reactions such as Suzuki-Miyaura coupling and Stille coupling.

• The choice of reaction depends on the specific goals of the project and the starting materials involved.

• I am always willin...read more

Understanding IR and NMR values helps in identifying possible products of reactions in chemistry.

• IR values can help identify functional groups present in a molecule

• NMR values can help determine the structure of a molecule by showing the connectivity of atoms

• Possible products of reactions can be predicted by analyzing the changes in IR and NMR spectra

• For example, a reaction between an alcohol and a carboxylic acid may r...read more
