- Overman Rearrangement - Organic Chemistry Portal
The Overman Rearrangement allows the conversion of readily available allylic alcohols into allylic amines by a two-step synthesis involving the rearrangement of an allylic trichloroacetimidate to an allylic trichloroacetamide with clean 1,3-transposition of the alkenyl moiety

- Olefin Metathesis, Grubbs Reaction - Organic Chemistry Portal
Olefin Metathesis Grubbs Reaction Olefin Metathesis allows the exchange of substituents between different olefins - a transalkylidenation This reaction was first used in petroleum reformation for the synthesis of higher olefins (Shell higher olefin process - SHOP), with nickel catalysts under high pressure and high temperatures Nowadays, even polyenes with MW > 250,000 are produced
- Directed Ortho Metalation - Organic Chemistry Portal
Directed ortho Metalation (DOM) The reaction of an alkyllithium compound with an arene bearing a "Directed Metalation Group" (DMG) normally leads to an ortho -metalated intermediate Good DMG's are strong complexing or chelating groups that have the effect of increasing the kinetic acidity of protons in the ortho -position The ortho -metalated intermediate can be reacted with a variety of
- Henry Reaction - Organic Chemistry Portal
Henry Reaction The Henry Reaction is a base-catalyzed C-C bond-forming reaction between nitroalkanes and aldehydes or ketones It is similar to the Aldol Addition, and also referred to as the Nitro Aldol Reaction If acidic protons are available (i e when R = H), the products tend to eliminate water to give nitroalkenes Therefore, only small amounts of base should be used if the isolation of
