Aiming to address energy related chemical processes, such as methane oxidative

oligomerization and water oxidation, developed and studied the reactivities of a

series of rare and important organometallic complexes which are stabilized by

m ultidentate N-donor ligands.

• Light induced ethane formation from monomethyl Pd complexes.

Two organometallic complexes PdI I R1R2 (R1 = Me, R2 = Me/Cl) stabilized by N,N -di-

isopropyl-2,11-diaza[3.3](2,6)pyridinophane (iPrN4) were synthesized, and oxidized

to PdI I I and PdIV chemically and/or electrochemically. The products were isolated and

f ully characterized by various techniques, including: CV, UV-vis, X-Ray crystography,

ESI-MS and elemental analysis. Interestingly, both Pd I I I and PdIV facilitate the C-C

bond formation via different mechanisms. The Pd I I I MeCl or PdI I I Me2 reactions involve

r adical mechanism when i r radiated with light, which were confirmed by the methyl

r adical t rapping with TMPO. The Pd IV MeCl and PdIV Me2 reactions use reductive

elimination mechanism when heated, as evidenced by the clean formation of MeCl

and ethane. This system allowed us to study the C-C/C-X bond formation mediated

by Pd of different oxidation states in the identical ligand environment for the first

t ime. Particularly remarkable is the observation for the rare ethane formation from

a monomethyl Pd complex. Such t ransformation has direct implications into catalyst

development for oxidative oligomerization of methane in particular and oxidatively-

induced Pd-catalyzed C–C bond formation reactions in general.

• The fi rst well defined PdIV p roducts from aerobic oxidation of Pd I I p recursors.

(Me3tacn)PdI I Me2 ( Me3tacn = N,N ,N -t r imethyl-1,4,7-t r iazacyclononane) was

oxidized by O2 t o form the well defined [(Me3tacn)PdIV Me 3] +, which gave quantitative

formation of C-C bond forming product under elevated temperature. The aerobic

oxidation likely involves an inner sphere oxidation by O 2, as evidenced by the spin

t rapping of oxidized intermediate by DMPO. The palladacycle complex

( Me3tacn)PdI I (CH 2CMe2C6H 4) is readily oxidized by O2 to give the

[(Me3tacn)PdIV (OH)(CH 2CMe2C6H 4)] +. This represents the fi rst example of aerobic

oxidation of PdI I t o form an isolable PdIV -hydroxide complex. Thermolysis of the Pd IV

leads to the selective Caryl -O reductive elimination of 2-tert-butyl-phenol in 55%

y ield, while no Calkyl -O bond elimination products were detected. Overall, this is a

r are example of C-O bond formation initiated by aerobic oxidation of a Pd I I p recursor.

T he work was published as the cover paper in the journal of Organometallics.

• Biometallic water oxidation catalyst development.

This project aims to design bimetallic complexes that can be applicable as catalysts

for water oxidation to produce oxygen. Such metallic catalysts would eventually

p rovide a novel pathway toward using solar energy as a renewable and “green”

energy source and find application in the design of a new type of photovoltaic fuel

cells. To this purpose, 2,8-di-n-butyl-4,6-bis(2-bis(6-methyl-2-

pyridylmethyl)aminomethyl- 6-methyl-4-pyridyl)dibenzofuran, a bimetallic complex

w ith dibenzofuran as linker, was synthesized via a 8 step route. The crystal

s tructure indicates that the dibenzofuran linker projects the two metal ions too far

apart from each other. Computational study (Gaussian) indicates that the energy

barrier to bring the two metal centers close enough for potential synergic effect is

p rohibitively high. This study nevertheless helped us to realize the importance of

computational studies in finding suitable ligands for our water oxidation catalyst

development.

Using mechanistic methodologies, we proposed the mechanism for hydride reduction

of NAD + analogues by isopropyl alcohol. Observed pseudo-first-order rate constants

( k obs) of the hydride-t ransfer reactions from isopropyl alcohol (i-PrOH) to two NAD +

analogues, 9-phenylxanthylium ion (PhXn +) and 10-methylacridinium ion (MA +),

were determined at various temperatures in i-PrOH containing various amounts of

MeCN or water. The work was published as the featured article in Journal of

O rganic Chemist ry.
