Non-metal catalysis may provide new and green methods for obtaining bioactive heterocycles. Many catalysts contain metals, which can be toxic, energy intensive to remove, and require mining of the source materials. By utilizing metal-free catalysts we avoid these issues. This book explores the use of non-metal catalysts when synthesizing various heterocyclic structures with bioactivity.
This book provides readers with the knowledge they need to integrate sustainable approaches into their work. Sections cover different aspects of green methods such as microwave irradiation and ultrasound sonication, some of which mostly contain solvent-free reaction conditions or water as solvent and ionic liquids, for synthesizing different compounds. Bringing together the knowledge of an expert team, this book provides a comprehensive overview of the use of green chemistry techniques, which have been frequently used in recent years, providing fewer chemicals, less energy, higher yield, etc. This book supplies a useful guide for all academic and industrial researchers across green and sustainable chemistry, medicinal chemistry, environmental chemistry, and pharmaceutical science.
In the 19th century Hungary witnessed unprecedented social, economic and cultural development. The country became an equal partner within the Dual Monarchy when the Austro-Hungarian Compromise of 1867 was concluded. Architecture and all forms of design flourished as never before. A distinctly Central European taste emerged, in which the artistic presence of the German-speaking lands was augmented by the influence of France and England. As this process unfolded, attempts were made to find a uniquely Hungarian form, based on motifs borrowed from peasant art as well as real (or fictitious) historical antecedents. "Motherland and Progress" – the motto of 19th-century Hungarian reformers – reflected the programme embraced by the country in its drive to define its identity and shape its future.
This annual review of the literature provides a comprehensive and critical survey of a vast field of study involving organophosphorus compounds, ranging from phosphines, phosphine-related P–C bonded compounds and their chalcogenide derivatives, phosphonium salts and P-ylides, to tervalent and quinquevalent phosphorus acid derivatives and penta- and hexa-coordinated phosphorus compounds. Recent developments in applications as reagents in green synthetic procedures are also given. With an emphasis on interdisciplinary content, this book will appeal to the worldwide organic chemistry and engineering research communities.
This book looks back on thirty-five years of microwave (MW) chemistry and explains how the application of the MW technique became an integral part of R&D, eventually becoming recognized in industry. Further, it details how MW chemistry has undergone a dynamic development in the past three decades, one driven by the advent of increasingly sophisticated professional MW reactors in place of the kitchen MW ovens used in earlier years. A major part of the book shows how substitutions, esterifications, amidations, hydrolyses, alkylations, eliminations, dehydrations, condensations, cyclizations, C–C couplings and the modification of heterocycles can be performed advantageously under MW irradiatio...
Updated annually, this directory provides information on over 150 US and over 250 international chemical engineering programmes.
Provides in depth reviews on current progress in the fields of asymmetric synthesis, organometallic chemistry, bioorganic chemistry, heterocyclic chemistry, natural product chemistry, and analytical methods in organic chemistry. Each issue is edited by an appointed Executive Guest Editor
This up-to-date faculty directory lists the contact information of all the faculty members, placement administrators, and student organizations of almost 500 worldwide universities and technical institutes offering chemical engineering curricula. This offers a comprehensive reference tool that is unique and valuable, in that there is no such directory available on chemical engineering. The indices make it easy to find the current affiliation of any chemical, biological and environmental engineering faculty by listing in alphabetical order.
