Book Description
This book discusses the developments in the synthesis and functionalization of different heterocycles based on the formation of carbon-carbon (C-C) and carbon-heteroatom (C-X) bonds using cross-dehydrogenative coupling (CDC). Consisting of 13 chapters, the book systematically describes the advances in the synthesis and functionalization of nitrogen, oxygen, and sulfur-containing heterocycles. It also discusses the various mechanistic pathways to help readers gain an in-depth understanding of the CDC reactions of heterocycles. Lastly, in order to promote green chemistry, it addresses a range of metal-free CDC reactions of heterocycles – an area that has attracted significant attention in both academic and industrial research.

Book Description
"Cross-Coupling Reactions: An Overview opens with an overview of the fundamentals and applications of the young and fast developing area of transition metal catalyzed/mediated oxidative (dehydrogenative) C-H/C-H coupling reactions between two (hetero)arenes. Continuing, the authors highlight the recent advances regarding the ligand supported transition metal-catalyzed domino (cascade) or one-pot syntheses of various heterocycles involving cross-coupling reactions. The recent advances in Cu catalyzed tandem reactions for heterocycle synthesis are also addressed. Cu metal chemistry has garnered attention as a potential alternative to precious transition metals, being cheaper, more sustainable and more easily available. A comprehensive account of research on green chemical routes is provided, involving various palladium metal-based catalysts utilized in facilitating cross-coupling reaction in aqueous media. Reported decarboxylative cross-coupling reactions are discussed along with suitable examples, focusing on their mechanism of action"--

Book Description
Heterocycle synthesis is one of the largest areas of modern organic chemistry. Heterocycles have a broad range of applications including pharmaceuticals, agrochemicals and dyes, and are the core structure to around 90% of naturally-occurring molecules. Transition metal catalysts have become favoured in heterocycle synthesis, not least because of their low cost, but also due to their relatively low environmental toxicity and biocompatibility. This book presents an overview of the state-of-the-art in transition metal catalysis for heterocycle synthesis. Each metal is discussed in turn, presenting a comprehensive source of information on the use of zinc, iron, copper, cobalt, manganese, and nickel in a sustainable and economic manner. Referencing the latest primary literature, and authored by active researchers in the field, this book is a must-have resource for anyone wishing to undertake an economic and sustainable approach to heterocycle synthesis.

Book Description
This thesis focuses on the development of new methods of functionalizing carboranes using o-carboryne intermediates. Functional carboranes are now finding a broad range of applications, including organic synthesis, drug design, polymers, catalysis, metal−organic frameworks, electronic devices and more. However, the limited number of efficient synthetic methods for obtaining functional carborane materials has restricted their applications. The methodologies established in this thesis represent simple, yet powerful strategies to assemble previously inaccessible, useful complex molecules, which will also have a significant impact on future synthetic, cluster and materials chemistry. Moreover, it discusses the first method for the in situ generation of electrophilic boron radical using photocatalysis.

Book Description
Transition-Metal-Catalyzed C-H Functionalization of Heterocycles A comprehensive guide to recent advances in this field Constituting the majority of all known compounds, heterocycles are structures that incorporate one or more heteroatoms within their core, thus exhibiting properties that are quite different from their all-carbon analogs. They are fundamental to all fields of chemistry and, therefore, their synthesis and modification has attracted a great deal of attention in the recent years. In this vein, transition-metal-catalyzed C-H bond functionalization forms a crucial tool for generating and analyzing heterocyclic compounds. Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume Set, showcases diverse C-H functionalization methodologies and their incorporation into the latest research. The chapters serve as an essential tool depicting detailed site-selective functionalization of heterocyclic cores, along with a comprehensive discussion on their mechanistic approaches. Readers of Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume-Set will also find: A detailed introduction to C-H activation along with the mechanistic aspects of transition-metal-catalyzed C-H bond activation reactions Easy-to-use structures with each chapter dedicated to a type of heterocycle and its specific functionalization methodologies A leading team of international authors in C-H bond functionalization Transition-Metal-Catalyzed C-H Functionalization of Heterocycles, Two-Volume-Set is a valuable guide for students and researchers in organic synthesis and process development, in both academic and industrial contexts.

Book Description
In this Special Issue, recent advances in cross-coupling reactions are presented in the form of original research articles, reviews, and short communications. These contributions cover different topics in this area, including novel coupling reactions, reaction conditions, synthetic alternatives, metal ligands, and applications for new pharmaceutical compounds and organic materials. In particular, the reviews deal with methodologies such as the synthesis of diarylketones through palladium catalysis and the most relevant examples of Suzuki–Miyaura and Buchwald–Hartwig coupling reactions in the synthesis of bioactive compounds. The synthetic utility of cross-coupling reactions for the synthesis of medium-size rings and the utility of Stille and Suzuki coupling reactions for the synthesis of new molecular machines based on sterically hindered anthracenyl trypticenyl units are also summarized. The original research articles present the synthesis of 2-alkynylpyrrols by inverse Sonogashira coupling and the synthesis of indoles under oxidative dearomative cross-dehydrogenative conditions. The efficient combination of iridium-catalyzed C–H borylation of aryl halides with the Sonogashira coupling and a sequential iridium-catalyzed borylation of NH-free pyrroles followed by a Suzuki–Miyaura reaction are included. The synthesis of aryl propionic acids, a common structural motif in medicinal chemistry, and the synthesis of new organic dyes are also covered.
