The recent advances in asymmetric organocatalysis using eutectic mixtures as a reaction medium are revised this mini-review. In addition, the first enantioselective transformations chiral solvents, which play role of green and organocatalyst, described. minireview we intend to deepen not only synthetic aspects mixtures, but also fundamental issues that seem be essential for successful developme...

Deep eutectic solvents (DESs) are formed by a hydrogen bond donor and an acceptor. The interactions between these two components significantly depress the melting temperature of mixture. DESs have been used as alternative for organic in various branches chemical industry. Many very hygroscopic water is known to change properties DESs, but there has neven systematic study performed on deliquesen...

The use of Reactive Deep Eutectic Solvents (RDESs) in the preparation polar head modified phospholipids (PLs) with phospholipase D (PLD)-catalyzed biotransformations has been investigated. Natural phosphatidylcholine (PC) submitted to PLD-catalyzed transphosphatidylations using a new reaction medium composed by mixture RDES/buffer. Instead exploiting deep eutectic solvents conventionally, just ...

Introduction . Natural deep eutectic solvents (DESs) are promising extractants for many biologically active substances from plant raw materials. They biodegradable, safe, stable, their production is affordable and easily feasible, the extraction efficiency comparable to known organic solvents. In this regard, interest in has been steadily growing recent years, they being used various fields of ...

Olivine-type LiMnPO₄/C nanorods were successfully synthesized in a chloride/ethylene glycol-based deep eutectic solvent (DES) at 130 °C for 4 h under atmospheric pressure. As-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and electroc...
