<p>This licentiate thesis is based on the development of catalytic reactions for the synthesis and application of organometallic reagents. By use of palladium pincer-complex catalysts, we have developed an efficient procedure for the synthesis of allylboronates starting from allylic alcohols. These reactions were further extended by including various one-pot multi-component reactions, using the in situ generated allylboronates. Furthermore, novel unsymmetrical palladium pincer-complexes were synthesized and studied in auto-tandem catalysis.</p>

These ligands, in addition to a Lewis acid coordination site, are equipped with a Lewis basic part in the 4-position of the oxazoline rings. Dual activation by means of this system was probed in cyanide addition to aldehydes. The second part is concerned with the synthesis of two pyridine-bis(oxazoline) ligands bearing bulky triazole groups in the 4

The reactivity of these bridged imines was then investigated using mercaptoacetic acid, and also dimethyl acetylenedicarboxylate (DMAD).

Pseudo-dynamic combinatorial chemistry (pDCC) combines the synthesis, screening and destruction of combinatorial libraries to kinetically resolve inhibitors based on their affinity for a target. In our proof-of-principle studies, a library of dipeptides was formed in the presence of a target, carbonic anhydrase (CA), and a destruction mechanism, a protease. Since the target and the protease were separated by a dialysis membrane, only the proportion of dipeptides that was not bound to the target was availa

Increasing the efficiency and durability of organic light-emitting diodes (OLEDs) has attracted attention recently due to their prospective wide-spread use as flat-panel displays. The performance and efficiency of OLEDs is understood to be critically dependent on the quality of the device heterojunctions, and on matching the ionization potentials (IP) and the electron affinities (EA) of the luminescent material (LM) with those of the hole (HTA) and electron (ETA) transport agents, respectively.
