Metals and Non-metals


Book Description

This title introduces the reader to the properties of different materials. Find out how metals are extracted, learn about different refining techniques and discover how metals might be used in the future.




Non-Metals


Book Description

Presents the structure, uses, and origins of some of the most common nonmetallic elements.




Chemistry of the Non-Metals


Book Description

The current textbook is an excellent inroduction to the chemistry of the non-metallic elements. The book begins by reviewing the key theoretical concepts of chemical bonding and the properties of different bonding types. Subsequent chapters are focused on reactions, structures and applications of the non-metallic compounds. Combining careful pedagogy and clear writing style, the textbook is a must-have for students studying inorganic chemistry.




Metals and Non-metals


Book Description

Design of new processes that avoid the use of toxic reagents has been the focus of intense research of late. Catalysis by metals and non-metals offers diverse opportunities for the development of new organic reactions with promising range of selectivities—chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. Furthermore, these transformations frequently occur under mild conditions, tolerate a broad array of functional groups, and proceed with high stereoselectivity. The area of catalysis is sometimes referred to as a ‘foundational pillar’ of green chemistry. Catalytic reactions often reduce energy requirements and decrease separations because of increased selectivity; they are also capable of permitting the use of renewable feedstocks of less toxic reagents or minimizing the quantities of reagents needed. New catalytic organic synthesis methodologies have, thus, offered several possibilities for considerable improvement in the eco-compatibility of fine chemical production. Hence, these catalytic methodologies have emerged as powerful tools for the efficient and chemoselective synthesis of heterocyclic molecules. Key Features: Presents the synthesis of different five-membered heterocycles. Contains the most up-to-date information in this fast-moving field. Covers novel catalytic approaches used in the study and application of catalysts in synthetic organic reactions. Presents new methodologies for the synthesis of heterocycles.
