Discovery
and development of catalytic methods for chemical
transformations not currently feasible.
Terminal
hydroxylation of linear alkanes, enantioselective
hydration of terminal olefins, alkyl C-H/olefin
coupling, and intramolecular s-bond
metathesis are examples of unsolved problems
in synthetic methodology. If these transformations
could be effected mildly and selectively, the
impact on chemical synthesis would be significant.
The fundamental premise of my approach is to
use the kinetic and thermodynamic preference
of certain transition metals for forming the
less sterically hindered primary organometallic
(C-M) intermediate as a basis for achieving
the desired selectivities. The challenge lies
in identifying novel strategies for forming
these C-M intermediates under functional group
tolerant conditions that enable functionalization
(e.g. C-M->C-OH) and catalyst regeneration.
My group will explore multi-variable catalytic
systems comprised of unconventional transition
metal complexes that are intended to work in
conjunction with nucleophilic/electrophilic
non-metal components to effect steps within
a catalytic cycle. As seen in Nature,
synergy within multi-component systems can achieve
uniquely mild and non-obvious solutions to challenging
problems in chemical reactivity.
