Phebox Ligands and Methods of Making Same
The Phebox ligand
Invention Summary:
Phebox ligands are organic complexes useful for a number of catalytic transformations of other organic molecules, including transformations of alkanes generally requiring harsh conditions. Since catalytic transformations using this class of ligands intrinsically involve the activation of C-H bonds,...

Iridium Catalyst for Dehydrogenative Dimerization of Ethylene to Yield 1,3-Butadiene
Schematic diagram of the catalytic dehydrogenative dimerization of ethylene to butadiene
Invention Summary:
1,3-Butadiene is a chemical building block, most notably known for the production of synthetic elastomers and polymers. Traditionally, 1,3-butadiene is produced as a byproduct of naphtha cracking for ethylene production. Due to new sources,...

Synthesis of p-Xylene by Dehydroaromatization of 3-Methyleneheptane obtained from Ethylene
Invention Summary:
p-Xylene is mostly produced from cracking of naphtha, but there is a need for new and cost-effective methods for the production. Indeed, conventional p-xylene synthesis requires toluene separation from refinery gasoline streams; performing a disproportionation reaction to yield a benzene fraction and a mixed xylene fraction; and...
