Phosph(III)azanes, featuring the heterocyclobutane P2 N2 ring, have now been established as building blocks in main-group coordination and supramolecular compounds. Previous studies have largely involved their use as neutral P-donor ligands or as anionic N-donor ligands, derived from deprotonation of amido-phosphazanes [RNHP(μ-NR)]2 . The use of ne...

Nasopharyngeal colonization by Streptococcus pneumoniae is a prerequisite for pneumococcal transmission and disease. Current vaccines protect only against disease and colonization caused by a limited number of serotypes, consequently allowing serotype replacement and transmission. Therefore, the development of a broadly protective vaccine against c...

Transition-metal-mediated cleavage of C-C single bonds can enable entirely new retrosynthetic disconnections in the total synthesis of natural products. Given that C-C bond cleavage inherently alters the carbon framework of a compound, and that, under transition-metal catalysis, the generated organometallic or radical intermediate is primed for fur...

Triene 6π electrocyclization, wherein a conjugated triene undergoes a concerted stereospecific cycloisomerization to a cyclohexadiene, is a reaction of great historical and practical significance. In order to circumvent limitations imposed by the normally harsh reaction conditions, chemists have long sought to develop catalytic variants based upon ...

The development of new methods for the asymmetric allylic alkylation of ketones, using either chiral ligands or chiral substrates, has been reviewed. Besides fundamental and mechanistic aspects, also applications of the new protocols as key steps in the synthesis of complex natural products have been discussed.
Prehodne kovine so v elementarnem stanju, kot soli in koordinacijske spojine pogoste sestavine kozmetičnih izdelkov (KI). V diplomski nalogi smo želeli ugotoviti, kako pester je njihov nabor na tržišču in kako raznolike vloge opravljajo v izdelkih. Izbrane KI smo razdelili v 11 skupin glede na namen njihove uporabe. Največ KI, 18, smo uvrstili med ...
V diplomskem delu obravnavam pregled kleščastih ligandov in njihovih kompleksov s kovinami prehoda. Najprej so predstavljene osnovne informacije o kleščastih ligandih in kompleksih. Sledi podroben pregled različnih načinov priprave le-teh. Zatem so opisani štirje različni načini za sintezo kleščastih kompleksov iz kleščastih ligandov in kovin preho...

Selective C-H bond functionalization catalyzed by metal complexes have completely revolutionized the way in which chemical synthesis is conceived nowadays. Typically, the reactivity of a transition metal catalyst is the key to control the site-, regio- and/or stereo-selectivity of a C-H bond functionalization. Of particular interests are molecules ...

In this review, we present analysis of absorption and circular dichroism spectra of disordered langasite crystals with the calcium gallium germanate structure, whose structures have no screw axis. We consider results of original research concerned with spectroscopic characteristics of undoped and transition metal-doped langasite crystals. Structura...
