Abstract: AbstractTwo types of chromium catalysts bearing pyridine and amine based SNS ligands under the title of (pyridine-SNS-alkyl/CrCl3) and (amine-SNS-alkyl/CrCl3) were synthesized. Different thiolates such as octyl, pentyl, butyl, cyclohexyl and cyclopentyl thiolates were reacted with… read more here.

Abstract: Abstract A family of phenoxy-imine-ether ligated Ti complexes for selective ethylene trimerization have been developed from highly active bis(phenoxy-imine) early transition metal ethylene polymerization catalysts. The Ti complexes, after activation with methylaluminoxane (MAO), selectively trimerized… read more here.

DOI: 10.1021/acscatal.7b04026
Abstract: Computational design of molecular homogeneous organometallic catalysts followed by experimental realization remains a significant challenge. Here, we report the development and use of a density functional theory transition-state model that provided quantitative prediction of molecular… read more here.
