Barry Trost

American organic chemist Barry Trost introduced the principle of atom economy in the early 1990s. This concept became a foundational rule of green chemistry, emphasizing that chemical reactions should maximize the use of all starting materials.

Trost is widely recognized for developing palladium-catalyzed allylic alkylation reactions. This method allows chemists to efficiently form carbon-carbon bonds, a crucial step in synthesizing complex organic molecules.

Barry Trost has been a professor of chemistry at Stanford University for decades. His laboratory at Stanford focuses on advancing synthetic organic chemistry and sustainable chemical processes.

The atom economy principle measures how much of the reactants end up in the final product versus becoming waste. Trost's concept forces chemists to design cleaner reactions, drastically reducing hazardous waste in pharmaceutical and chemical manufacturing.
