Abstract In der Vergangenheit wurde eine Vielzahl von Methoden zur Verwendung Kohlendioxid in organischen Synthese entwickelt. Trotz breiten Gesamtverfügbarkeit CO 2 auf Erde ist sein Einsatz als Reaktant, insbesondere Synthesechemie, recht selten. den letzten 35 Jahren intensiv daran geforscht, kosten‐ und energieeffiziente katalytische Prozesse zu finden, um Carbonsäuren, Estern, Lactonen Polymeren umzusetzen. Dieser Aufsatz fasst die bis heute vorhandenen homogenkatalytischen Routen C 1...
Aqueous hydrogenation of bio-based succinic acid has been reported for the production value added chemicals, e.g. 1,4-butanediol, tetrahydrofuran, γ-butyrolactone, 2-pyrrolidone or N-methyl-2-pyrrolidone. A variety heterogeneous metallic catalysts, active under quite severe conditions have previously studied, whereas research into organometallic complexes is thus far limited to solvent reactions aqueous producing acid.
Hydrosilylation of C–C multiple bonds is one the most important applications homogeneous catalysis in industry. The reaction characterized by its atom-efficiency, broad substrate scope, and widespread application. To date, industry still relies on highly active platinum-based systems that were developed over half a century ago. Despite rapid evolution vast synthetic applications, development fundamental understanding catalytic pathway has been difficult slow, particularly for industrially...
Heteroatom-participated lignin depolymerization for heterocyclic aromatic compounds production is of great importance to expanding the product portfolio and meeting value-added biorefinery demand, but it also particularly challenging. In this work, synthesis pyrimidines from β-O-4 model compounds, most abundant segment in lignin, mediated by NaOH through a one-pot multi-component cascade reaction reported. Mechanism study suggests that transformation starts NaOH-induced deprotonation Cα-H...
Stimuli-responsive aggregation-induced emission (AIE) materials are highly sensitive and rapidly responsive to external signals, making them ideal solid for anti-counterfeiting encryption. However, the limited conformational packing variations resulting from regio-isomerization with a single substituent restricts stimuli-responsive behavior of these materials. In this work, several AIE-active regio-structural isomers based on salicylaldehyde Schiff base scaffold have been straightforwardly...

Complexes of the general formula [MoO2X2L2] (X=Cl, Br, Me; L2=bipy, bpym) have been prepared and fully characterized, including X-ray crystallographic investigations all six compounds. Additionally, highly soluble complex [MoO2Cl2(4,4′-bis(hexyl)-2,2′-bipyridine)] has synthesized. The reaction complexes with tert-butyl hydroperoxide (TBHP) is an equilibrium reaction, leads to MoVI η1-alkylperoxo that selectively catalyze epoxidation olefins. Neither Mo−X bonds nor Mo−N are cleaved during...
Metal–organic frameworks (MOF) are becoming a more and important class of functional materials. Yet, very often, the synthesis MOFs is not easy to control requires profound knowledge experience in solid state chemistry. One most frequently used metal connectors so-called 'paddle-wheel' (PW) unit, which well-known molecular compound type inorganic coordination Depending on ligands, geometry PWs strictly directs assembly ordered networks. This review focuses question, what extent network...
Abstract The combination of pentaerythritol with nucleophilic halide salts such as n Bu 4 NI is used a dual catalyst system for the cycloaddition carbon dioxide (CO 2 ) broad range organic epoxides yielding respective cyclic carbonates. Due to synergistic effects organocatalysts, excellent yields and selectivities could be achieved under mild reaction conditions. Moreover, nontoxic, cost‐efficient, readily available easily recyclable without significant loss reactivity, representing an...
Abstract Hydroxy‐functionalized mono‐ and bisimidazolium bromides were synthesized applied as catalysts for the cycloaddition of CO 2 epoxides to cyclic carbonates. A catalyst screening showed influence number protic hydrogen atoms at cation activation epoxides. The most active operates very mild reaction conditions (70 °C, 0.4 MPa ) can be easily recycled ten times without loss activity.

Self-assembled metallocages are very promising drug-delivery systems among supramolecular complexes. Thus, exo-functionalized Pd2 L4 (L=ligand) cages were synthesized and characterized, the encapsulation of anticancer drug cisplatin in their cavity has been documented. The antiproliferative effects combination with examined vitro cancer cell lines, while fluorescence microscopy was used to monitor uptake. Notably, hydroxymethyl-functionalized Pd(II) cage encapsulating showed improved...
The epoxidation of olefins catalyzed by molecular transition metal compounds is a research field, which has been extensively studied over the past forty years. To date, numerous types complexes have presented as widely applicable and highly efficient. This Perspective Article gives summary most active catalysts for some frequently applied olefins, such cyclooctene, 1-octene, prochiral industrially relevant olefins.
