Tris[2-(2-methoxyethoxy)ethyl]amine is a complexant phase-transfer catalyst that combines the effectiveness of cryptands and crown ethers with the open chain structure of polyethylene glycols.
First commercialized by Rhone Poulenc as TDA-1 in the 1980’s, this phase-transfer catalyst enjoyed many successful PTC applications, including some surprising ones like the Ullmann Reaction and even the Grignard Reaction. When Rhone-Poulenc discontinued TDA-1, PTC applications decreased.
Recently, we received information that tris[2-(2-methoxyethoxy)ethyl]amine may become available again commercially.
If your company would like to screen this highly effective phase-transfer catalyst for your processes in development, please contact Marc Halpern of PTC Organics.
