Descrizione generale

Learn More at the Professor and Product Portal of Professor Bruce Lipshutz.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product TPGS-750-M is a lead surfactant for many transition metal-catalyzed cross-couplings and has been enhanced for catalytic efficiency. Find details here.

Applicazioni

On the Way Towards Greener Transition-Metal-Catalyzed Processes as Quantified by E Factors
Second generation amphiphile which forms micelles upon dissolution in water allowing a variety of cross-coupling reactions to take place in water instead of organic solvent.

Included among the possible reactions are:
  • Olefin metathesis
  • Pd-catalyzed cross coupling reactions including Heck, Suzuki-Miyaura, Sonogashira and Buchwald-Hartwig reactions
  • C-H activation reactions

Second generation amphiphile for cross-coupling reactions in water
