Description

The Nysted reagent is a reagent used in organic synthesis for the methenylation of a carbonyl group. It was discovered in 1975 by Leonard N. Nysted in Chicago, Illinois. It was originally prepared by reacting dibromomethane and activated zinc in THF.
A similar reagent is Tebbe's reagent.In the Nysted olefination, the Nysted reagent reacts with TiCl to methylenate a carbonyl group. The biggest problem with these reagents are that the reactivity has not been well documented. It is believed
