Lecture 1: Key Concepts in Stereoselective Synthesis
... Radical decarboxylation is an attractive method for organic synthesis. The major advantages are that carboxylic acids are abundant and inexpensive, the radical intermediates produced can be converted into many chemical products and that CO2 is produced as a traceless byproduct. While there are many ...

Synthesis and Characterization of Dendrimer Templated Supported
... In this route, ligand-stabilized molecular clusters, typically stabilized by CO ligands, are deposited onto oxide supports and thermally activated to remove the ligands. This method has led to the preparation of several bimetallic Pt-Au/SiO2 catalysts in which the metals are intimately mixed after l ...
