Knoevenagel condensation was discovered in the 20th century, and since then it has been present in a wide range of reactions in organic chemistry due to its potential for forming carbon-carbon bonds. This reaction is usually carried out between aldehydes or ketones and active methylene compounds in the presence of Lewis acids or basic catalysts. The great advantage of this reaction is that can be carried out in mild cond Read More

In the last two decades, considerable attention was devoted to the use of ionic liquids (ILs) in organic syntheses. Initially, they were applied as solvents, often playing the role of the catalyst as well. Nowadays, there is a growing trend to apply the ILs as cosolvents, additives, or catalysts in organic reactions. The spread of ILs justified several reviews on reactions carried out in the presence of different ILs. However, there is Read More

Catalytic asymmetric hydrosilylation based on the use of inexpensive and handleable hydridic silanes is a very useful reaction in organic chemistry which has become the subject of special interest because of the intrinsic peculiarity of economic efficiency and environmental friendliness. Recently, a lot of structurally diverse organocatalysts have been designed and applied to this chemistry. Enantiopure organocatalysts su Read More

Background: Ammonium bifluoride is a reagent widely used in organic synthesis; however, the systematic collection and classification have not been covered until now. Methodology: In this review, we aim to systematically summarize the application of ammonium bifluoride in organic synthesis. Conclusion: It can be used for deprotection of hydroxyl protected groups (esp. Silyl protection). It is also used for introducing F Read More

Background: Dendritic self-host phosphorescent Iridium materials, which generally consist of an Iridium light-emitting core, dendrons(branches) and surface groups, are a kind of novel and effective triplet emission materials for non-doped solutionprocessed organic light-emitting diodes (OLEDs). Methodology: Iridium light-emitting cores can harvest singlet and triplet excitons to obtain a theoretical internal quantum efficiency of 1 Read More

Dendrimers are a kind of macromolecule materials composed of central nuclei, repeating units and terminal groups. The dendritic topology leads to unique threedimensional architecture with mono-distribution at the nano-scale. Considerable attention has been focused on the high-efficient synthesis and potential applications of dendrimer in various fields such as biomedicine, catalysts, membrane materials and biosensors.

An efficient protocol for the intermolecular amidoselenation of alkenes with diphenyl diselenides and acetonitrile has been developed that affords a series of β-amidoselenides in high yields under mild conditions. The preliminary experimental results support the involvement of active benzyl radical species, and a radical pathway was therefore proposed for the reaction.
