With a total of 2 patents to her name, her work has the potential to impact agricultural practices positively.

Latest Patents

Melissa Lee's latest patents focus on the preparation of halogen analogs of picloram. The methods she developed include several chemical process steps. These steps involve introducing a phthaloyl group onto the 4-amino substituent of picloram acid, picloram ester, or the nitrile analog of picloram. Additionally, her methods add two fluorine atoms at the 5,6-positions of the pyridine ring using halex fluorination chemistry. Following this, the phthaloyl group is removed, and the ester or nitrile substituent is hydrolyzed. Chlorine or bromine is then added to the 6-position by treatment with an acid and water. Finally, the 5-fluoro-6-(bromo or chloro)picloram acid produced is esterified to create a 5-fluoro-6-(bromo or chloro)picloram ester.
