Professor Andy A. Thomas

Andy A. Thomas is a U.S. chemist and currently an assistant professor at Texas A&M University. His research focuses on the development of synthetic methodologies using highly reactive intermediates.[1] Currently, he is investigating reaction site selectivity using lithium reagents,[2] intercepting ozonolysis intermediates,[3] and work in the area of ligand design.[4]

Early Life and Education[edit]

Andy Thomas was born in Oakboro, North Carolina in 1988.

In 2006, he attended the University of North Carolina at Charlotte,obtaining his B.S. and M.S. with Prof. Craig A. Ogle.[5] In 2011, he joined Prof. Scott E. Denmark at the University of Illinois at Urbana-Champaign, where he earned his PhD by studying the transmetalation step of the Suzuki-Miyaura cross-coupling reaction and characterizing the pre-transmetalation intermediates.[6][7] In 2017, he began his post-doctoral fellowship at Massachusetts Institute of Technology with Prof. Steven L. Buchwald, where he designed ligands for copper hydride catalyzed hydroamination.[8]

In 2020, he began his independent career as an Assistant Professor at Texas A&M University.[9]

Independent Career[edit]

Lithium Chemistry[edit]

Lithium Dendrites[edit]

In 2022, Thomas and co. designed a method to recrystallize and make lithium dendrites- a lithium source that had 100 times more surface area than lithium powder. Furthermore, the dendrites proved to be highly effective in preparing organolithium reagents.[10]

Site Selectivity[edit]

In 2023, a method to functionalize remote positions on heterocycles using lithium bases was designed.[11]

Ozonolysis[edit]

Primary Ozonides[edit]

In 2023, a method to produce syn-hydroxyls via capture of primary ozonide intermediates was described.

Research[edit]

Currently, Thomas is leading a research group that specializes in synthetic methods using reactive materials.[12] Some major topics Thomas and his research group are focusing on are:

  • Synthetic methods for organolithium reagents
  • Constructive Ozonolysis
  • Synthesis of Reactive Materials
  • Design of Rapid-Injection NMR system
