Research Interests:
Research in the Jordan group is focused on synthetic and mechanistic organometallic chemistry. The central theme of this work is the interplay between the structures and reactivity of organometallic compounds, especially in systems that are relevant to catalysis. We design reactive organometallic complexes for use as practical catalysts and synthetic reagents, and as probes of fundamental mechanistic issues in catalysis. We use a wide range of synthetic and spectroscopic methods for the manipulation and characterization of reactive materials, most notably anaerobic synthesis techniques, NMR spectroscopy, molecular modeling and X-ray crystallography. Our current efforts are focused on four major topics: catalytic olefin polymerization, stereoselective catalysis, the design of super-electrophilic main group complexes, and the catalytic chemistry of metal carborane complexes.
 
Catalysts derived from Cp2ZrX2 and other "metallocene" complexes exhibit high activity for polymerization of simple non-functionalized olefins. Metallocene systems are "single-site" catalysts and produce polyolefins with narrow molecular weight and composition distributions. We have shown that the active species in Cp2ZrX2-based catalysts are Cp2ZrR+ cations which are generated from Cp2ZrX2 precursors by alkylation and R-/X- abstraction reactions. We have studied the chemistry of cationic metal alkyls to develop a detailed understanding of the structural and electronic features that are necessary for olefin polymerization activity by metallocenes. We are now exploiting these principles to design new catalysts based on both early and late transition metals and a variety of non-Cp ligands. We are particularly interested in the design of catalysts that will polymerize functionalized olefins such as vinyl chloride or vinyl acetate by insertion mechanisms, in order to prepare new polymers whose properties are superior to those of polymers produced by radical polymerization.
 
We are also investigating fundamental issues in olefin polymerization. For example, we have designed model d0 metal olefin complexes in which the metal-olefin bonding is enhanced by chelation. Structural and spectroscopic studies of these systems are providing new insights to how d0 metals activate olefins for insertion and polymerization.
 
We have used insights gained from our studies of cationic metallocene complexes to develop many new classes of reactive metal alkyls. For example, by utilizing carborane ligands in place of Cp- ligands, we have constructed neutral (C2B9H11)( C5R5) M(R) complexes which have the same structures, electron count, and frontier orbital properties as Cp2Zr(R)+ cations. The carborane systems exhibit unique behavior in catalysis, e.g. "self correcting" behavior in which a catalyst "error" that would normally lead to side products triggers a cascade of reactions that modify the catalyst structure and enhance selectivity. More recently we have prepared novel low-coordinate cationic main group alkyls, e.g. {RC(NR')2}Al(R)+ which are of interest as super electrophilic Lewis acids.
