Organocatalysis are an important tool for greener catalytic processes due to the lack of precious metals used. This book explores different organocatalysts and their use in synthesis. Topics covered include zwitterionic imidazolium salt catalysts, asymmetric catalysts in aqueous media, beaker yeast catalysis, organocatalysts for Aldol and Michael reactions, amino acid-based organocatalysts, and Bronsted acidic surfactant organocatalysts.

Описание: A must-have resource for all the researchers working in the organofluorine and related fields This timely two-volume set uniquely focuses on emerging fluorinated motifs beyond R-CF3 and R-F, like R-CF2H, R-OCF3, R-SCF3 and R-SF5. It also offers descriptions of the properties, synthesis, and applications of these emerging fluorinated motifs in order to help readers design new chemical entities, while providing new interest for researchers in organofluorine chemistry and new tools for those in other areas. Emerging Fluorinated Motifs: Synthesis, Properties and Applications begins with a description of carbon-linked fluorine-containing groups that include monofluoromethyl and difluoromethyl groups. It then details combinations of heteroatoms, Oxygen, Sulfur, Selenium, Nitrogen, and Phosphorus with fluorine-containing groups, outlining subsections of the most popular current motifs. Fluoroalkyl ethers, thioethers, and the recent blossoming of the SF5 unit is covered. Other chapters look at: selenium-linked fluorine-containing motifs; construction of N?CF2H, N?CF3, N?CH2CF3 motifs; and the synthesis and applications of P Rf-containing molecules. -Focuses on the synthesis, properties, and applications of emerging fluorinated motifs -Covers carbon-linked fluorine-containing motifs, oxygen-linked fluorine-containing motifs, sulfur-linked fluorine-containing motifs, and more -Appeals to academic and industrial researchers working in organic chemistry, medicinal chemistry, food chemistry, and materials science -Edited by world-renowned experts in organofluorine chemistry Emerging Fluorinated Motifs is intended for academic research institutes, university libraries, researchers, graduate students, postdoctors, and researchers in the chemical industry.

Описание: This book provides an excellent overview on state-of-the-art of modern organocatalysis. It will be of interest to those who want a general overview of the topic, but also to those who want to learn more about the state-of-the-art, current trends and perspectives in this highly dynamic field of research.
Organocatalysis is considered today one of the three pillars in asymmetric catalysis, along with biocatalysis and organometallic catalysis. The possibility to combine organocatalysis with radical chemistry, photocatalysis and enabling technologies opened new avenues in organic synthesis.

Описание: For over 150 years Britain`s railways have relied on a system of semaphore signalling, but by 2020, all semaphore signals and lineside signal boxes will be gone. This book provides a pictorial record of the last operational signalling and infrastructure on Britain`s railway network, as it applied to the former London, Midland and Scottish Railway.

Описание: This book proposes a novel concept for molecular recognition. In the field of asymmetric synthesis approaching the mature science, asymmetric discrimination and catalytic synthesis of chiral supramolecules still stand as unsolved problems. The extreme difficulty in asymmetric synthesis of such supramolecules may result from the mobile nature of supramolecular chirality. Here the author shows the first highly enantioselective synthesis of mechanically chiral supramolecules. In the presence of a chiral organocatalyst, a mechanically planar chiral rotaxane was obtained with p erfect enantiopurity (>99% ee) with an excellent selectivity. The dynamic and flexible recognition mode enabled asymmetric synthesis of supramolecules with conformational flexibility and mobility. The recognition mode of the catalyst is a contrast to the traditional static and rigid recognition mode of the typical conventional catalysts. The concept of dynamic molecular recognition will be adopted as a novel concept in a wide range of fields beyond the field of organic chemistry, including material chemistry, biochemistry, and medicinal chemistry.
