Metal-Carbon Bond Hydride Reagents in Organic Chemistry

Learn about the role of metal-carbon bond hydride reagents in organic chemistry, their importance in bimolecular elimination (E2) steps, nucleophilic addition, and nucleophile elimination. Discover how these reactions can lead to changes in bond polarity, enable the formation of larger organic species, and facilitate substitution at polar π bonds.

  6. Nucleophile Elimination Steps

  7. Importance of Nucleophilic Addition and Nucleophile Elimination • They can cause the number of bonds between two atoms of significantly different polarity to change, thus leading to reduction and oxidation reactions. Chapter 17 • They allow two relatively large organic species to be joined to make one even larger organic species. Chapters 18 & 21 • When nucleophilic addition and nucleophile elimination steps occur sequentially, substitution can take place at a polar π bond. Chapter 20 and 21
