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. |
