Abstract:

In this concise review, an emphasis is laid on the important role of superbases as catalysts and reagents in organic synthesis that so far remain underestimated. Diverse approaches to understand the superbasicity phenomenon are considered and the definition of superbase is given. Typical compositions of most widespread superbase systems are systematized and tabulated. The representative classic organic reactions assisted by superbases are surveyed.

This paper considers the synthesis and investigation of cyclic silicon-organic polymers with mono- and polycyclic fragments in the side chain. For obtaining monocyclic polymers, the hydrosilylation reaction of 1-hydro-3-vinylhexamethylcyclotetrasiloxane was used. The reaction was conducted in a CCl4 solution at 75°C in the presence of Speier’s catalyst (H2PtCl6  6H2O) to produce a viscous-flow at room temperature polymer. The polymers were studied by NMR spectroscopy. Poly(carbosiloxane) with cyclic fragments in the methyl-siloxane backbone was synthesized by the hydride polyaddition of divin

Here, we perform nonequilibrium thermodynamic calculations to assess the energetics of abiotic synthesis for a broad spectrum of small organic molecules under both cold oceanic and hydrothermal conditions on Enceladus.

The natural organics, for example, amino acids, small peptides, and fatty acids, acted as SDA for assembly of functional porous silica structures that induced further poly

AbstractMeteoritic organic material may provide the best perspective on prebiotic chemistry. Meteorites have also been invoked as a source of prebiotic material. This study suggests a caveat to extraterrestrial organic delivery: that prebiotic meteoritic organics were too dilute to promote prebiotic reactions. However, meteoritic material provides building material for endogenous synthesis of prebiotic molecules, such as by hydrolysis of extraterrestrial organic tars, and corrosion of phosphide minerals.

Abstract:

One-pot syntheses are a simple, efficient and easy methodology, which are widely used for the synthesis of organic compounds. Imidazoline is a valuable heterocyclic moiety used as a synthetic intermediate, chiral auxiliary, chiral catalyst and a ligand for asymmetric catalysis. Imidazole is a fundamental unit of biomolecules that can be easily prepared from imidazolines. The one-pot method is an impressive approach to synthesize organic compounds as it minimizes the reaction time, separation procedures, and ecological impact. Many significant one-pot methods such as N-bromosuccinimide mediated

Abstract:

In the nascent solar system, primitive organic matter was a major contributor of volatile elements to planetary bodies, and could have played a key role in the development of the biosphere. However, the origin of primitive organics is poorly understood. Most scenarios advocate cold synthesis in the interstellar medium or in the outer solar system. Here, we report the synthesis of solid organics under ionizing conditions in a plasma setup from gas mixtures (H2(O)−CO−N2−noble gases) reminiscent of the protosolar nebula composition. Ionization of the gas phase was achieved at temperatures up to 1

Abstract:

AbstrakSintesis ZSM-5 dilakukan dari metakaolin terdealuminasi tanpa penambahan templat organik. Sintesis dilakukan melalui pengaturan suhu hidrotermal mulai suhu 120oC, 150o, dan 170oC. Hasil sintesis dikarakterisasi dengan difraktometer sinar-X , spektrometer FTIR, dan adsorpsi/desorpsi nitrogen. Pengaturan suhu hidrotermal pada 120oC selama 24 jam belum menghasilkan ZSM-5, sedangkan sintesis pada suhu 150oC selama 24 jam diperoleh hasil ZSM-5 dengan kristal yang cukup baik. Hidrotermal pada 170o tetap dapat membentuk ZSM-5 dengan pengotor mordenit dan kurang kristalin dibandingkan sintesis

Abstract:

A synthesis efficiency algorithm, which must be based on concrete and reliable criteria, is essential for the evaluation and control of complex chemical synthesis, notably multicomponent reactions (MCRs). An algorithm has been developed to precisely evaluate even highly complex syntheses with regards to their synthesis efficiency Eff syn as a tool for strict compliance with green chemistry requirements, and for economic progress. The mathematical operations are highly suitable for electronic data processing (EDP). This algorithm is also suitable as a basis for fair cost assessment of complex c

Abstract:

The detection of pyrrole rings in numerous organic compounds with various pharmacological activities, emphasizes its huge importance in medicinal chemistry. Thus, the synthesis of pyrroles continues to arouse interest and Paal-Knorr condensation is considered to be the main synthetic route. A significant advance has been made since the MW activation was introduced in the organic synthesis which can be confirmed with the rapid growth of the published papers on that topic. Microwave irradiation is gaining popularity since faster reaction time, higher yields, easier work-up and reduced energy inp

Abstract:

AbstractInfrared spectroscopic observations have shown that complex organics with mixed aromatic-aliphatic structures are synthesized in large quantities during the late stages of stellar evolution. These organics are ejected into the interstellar medium and spread across the Galaxy. Due to the sturdy structures of these organic particles, they can survive through long journeys across the Galaxy under strong UV background and shock conditions. The implications that stellar organics were embedded in the primordial solar nebula is discussed.
