Fluorine is well-known as a very special element. Approximately 30% of agrochemicals and 20% of all drugs contain fluorine; most of those compounds have unique functions in biochemistry, pharmacy, and bioscience and those containing difluoromethyl functional groups often have irreplaceable roles. Therefore, the selective introduction of difluoromethylated functional groups into various aromatic substrates has significant practical application. This review describes recent advances in selective difluoroalkylation of aromatic substrates by using different catalytic strategies (cyclometalated ruthenium complex, transient regulating and visible-light-induced strategies).

: Iodine(III)-based reagents has been broadly used in oxidative reactions for the structural functionalization with several functional groups. Among the more relevant and useful synthetic transformations using these hypervalent γ 3 -reagents, it can be found the fluorination, chlorination, bromination as well as the iodination protocols. Herein, we present some of the most representatives oxidative halogenation procedures of arenes, olefins and alkynes dating from the oldest to the more recent advances in the area, highlighting the discovery and application of new iodine(III)-based halogenating species.

Peptides represent a promising class of biorecognition elements that can be coupled to electrochemical transducers. The benefits lie mainly in their stability and selectivity toward a target analyte. Furthermore, they can be synthesized rather easily and modified with specific functional groups, thus making them suitable for the development of novel architectures for biosensing platforms, as well as alternative labelling tools. Peptides have also been proposed as antibiofouling agents. Indeed, biofouling caused by the accumulation of biomolecules on electrode surfaces is one of the major issues and challenges to be addressed in the practical application of electrochemical biosensors. In this review, we summarise trends from the last three years in the design and development of electrochemical biosensors using synthetic peptides. The different roles of peptides in the design of electrochemical biosensors are described. The main procedures of selection and synthesis are discussed. Selected applications in clinical diagnostics are also described.

Recent Advances

High-performance electrolyte is still a roadblock for the development of rechargeable magnesium (Mg) batteries. Grignard-type electrolytes were once the only choice in the early stage of rechargeable Mg batteries research. However, due to their nucleophilic nature and high reactivity, Grignard-type electrolytes have inherent safety issues and low oxidation stability, which restrict the development of rechargeable Mg batteries in terms of practical application. Recently, emerging novel Mg battery systems such as Mg-S, Mg-O2/air batteries also require non‐nucleophilic electrolytes with high oxidation stability. This short review summarizes recent advances in non‐nucleophilic Mg electrolytes and aims to provide insights into electrochemical properties and active Mg ion structure of such electrolytes.

Functionalized mesoporous materials are widely used in the environmental field due to their excellent adsorption and catalytic properties. The materials with different functions are obtained by modifying mesoporous materials. In this paper, the preparation methods of functional mesoporous materials with functional groups, metal doping and acid modified were presented. This review focused on the main features and applied prospects of functionalized mesoporous materials under three producing methods. Recent advances of functionalized mesoporous materials in the fields of adsorption and catalysis have been summarized. Adsorption mainly refers to the treatment of heavy metals, organic contaminant, dyestuff and CO2. Finally, the trends and application foreground of functionalized mesoporous materials were elaborated in this paper, which provided reference and guidance for the development of functional mesoporous materials.
