Dendrimer-Induced Molecular Catalysis in Water: The Example of Olefin Metathesis
Written by Abdou K. Diallo on October 18, 2010 – 5:00 am -A dendritic nanoreactor (see graphic) constructed by 1→3 connectivity and terminated by 27 tetraethyleneglycol tethers induces ring-closing metathesis (RCM), cross metathesis (CM) and enyne metathesis (EYM) using low amounts of Grubbs-II catalyst in water and air, down to 0.04 % Grubbs catalyst for RCM. The dendrimer can be re-used at least 10 times without significant yield decrease.
