Preface

This book illustrates new findings on alkenes, including information on the synthesis of alkenes, olefins, and polyolefins.

Chapter 1 presents an overview of olefins and their preparation.

Chapter 2 shows the oxidation of alkenes as an important reaction used to develop epoxides, carbonyls, allylic compounds, 1, 2-diols, and so on. In this work, metal-catalyzed oxidation of alkenes is examined. This chapter highlights the metal-catalyzed green oxidation of alkenes and provides new strategies for the functionalization and transformation of alkenes.

Chapter 3 expresses the photo-redox process via single-electron transfer (SET). It studies the synthesis of targeted organic compounds due to their environmental friendliness and sustainability. According to this chapter, the construction of the C–N bond via visible-light-mediated difunctionalization of alkenes would be useful for medicinal and synthetic organic chemists and inspire further reaction development.

Chapter 4 describes the catalytic isomerization of olefins and their derivatives. According to this chapter, carbon-carbon double bond (CCDB) isomerization is a method for synthesizing new organic compounds from olefins and their derivatives based on C=C migration along the carbon chain and cis/trans transform. In fact, it plays a vital role in the fields of organic synthesis, synthesis of daily chemicals, development of raw oil, and synthesis of natural products. Chapter 5 presents research on extending alkenes' value chain to functionalized polyolefins. The chapter reviews the commercial specialty and functions of polyolefins as well as future prospects.

Finally, Chapter 6 discusses some industrial aspects of olefins' production and the process detail through naphtha feed.
