A Doubly Biomimetic Synthetic Transformation: Catalytic Decarbonylation and Halogenation at Room Temperature by Vanadium Pentoxide

, 2016
The halogenation of the C-H bond by metal-oxo-peroxo species and the decarbonylation of aldehydes by metal-peroxo species are performed routinely in biological systems. However, metal-mediated decarbonylative halogenation is unknown in nature.

Diastereoselective Halogenation Reactions

A review of the last 10 years of diastereoselective halogenation methods is presented. They have been divided by reactions into alkenes, alkynes, and heterocycles. In many of the cases, the use of transition metals is described.
