The design of synthetic routes by retrosynthetic logic is decisively influenced by the transformations available. Transition-metal-catalyzed C-H activation has emerged as a powerful strategy for C-C bond formation, with myriad methods developed for diverse substrates and coupling partners. However, its uptake in total synthesis has been tepid, part...

Cilj magistrskega dela je bil preučiti katalitske lastnosti kompleksov kovin prehoda s polipiridinskimi ligandi na izbranih modelnih reakcijah. Stabilni kompleksi kovin prehoda s piridinskimi strukturami kot podpornimi ligandi, so pomembne spojine, tako v homogeni kot heterogeni katalizi. Heksa(piridin-2-il)benzen je spojina s šestimi dušikovimi at...

Med pisanjem diplomske naloge sem pregledala znanstveno literaturo, ki se je vsebinsko navezovala na aktivacijo C–H vezi v prisotnosti prehodnih kovin kot katalizatorjev, s poudarkom na rutenijevi katalizi. Najprej sem opisala sintezo in lastnosti simetričnih heksaarilbenzenov ter omenila možno sintezno pot asimetričnih heksaarilbenzenov. V nada...

The most common reactive material used for the construction of a permeable reactive barrier (PRB) is zero valent iron (ZVI), however, its processing can generate corrosive effects that reduce the efficiency of the barrier. The present study makes a major contribution to understanding new reactive materials as natural and synthetic, easy to obtain, ...

This review consists of a compilation of synthesis methods and several properties of borohydrides beyond Groups I and II, i.e., transition metals, main group, lanthanides, and actinides. The reported properties include crystal structure, decomposition temperature, ionic conductivity, photoluminescence, etc., when available. The compiled properties ...

The "hydricity" of a species refers to its hydride-donor ability. Similar to how the pKa is useful for determining the extent of dissociation of an acid, the hydricity plays a vital role in understanding hydride-transfer reactions. A large number of transition-metal-catalyzed processes involve the hydride-transfer reaction as a key step. Among thes...

Despite the remarkable advances in the area of asymmetric catalytic oxidations over the past decades, the development of sustainable and environmentally benign enantioselective oxidation techniques, especially with the efficiency level similar to natural enzymes, still represents a challenge. The growing demand for enantiopure compounds and high in...

Obstaja veliko kompleksov kovin prehoda, ki se velikokrat uporabljajo v katalizi, zato je aktualna tudi priprava novih vrst kompleksov. Del teh so tudi kleščasti PNP, PCP in CNC kompleksi s kovinami. Kompleksi različnih kovin se zelo razlikujejo po stabilnosti, zato je njihova priprava in uporaba od tega zelo odvisna. Ker imajo kovine v teh komplek...

Metal ions play many critical roles in biology, as structural and catalytic cofactors, and as cell regulatory and signalling elements. The metal–protein affinity, expressed conveniently by the metal dissociation constant, K D, describes the thermodynamic strength of a metal–protein interaction and is a key parameter that can be used, for example, t...

Abstract—We have evaluated the polarity and degree of isomorphism in metastable aluminides with the L12 structure resulting from the solidification of superheated aluminum alloys with two transition metals: Al–Sc–Ti (Zr, Hf), Al–Ti–Zr (Hf), and Al–Nb–Ti (Zr). The degree of isomorphism has been shown to depend on the similarity of the dimensional an...
