Das, Tamal Kanti; Biju, Akkattu T. published the artcile< A Method for the Analysis of Free Carbenes Present after NHC-Organocatalyzed Transformations>, Reference of 112-63-0, the main research area is azaheterocyclic carbene organocatalysis thione.
In N-heterocyclic carbene (NHC) based organocatalysis, usually, the free carbene is generated in situ by treatment of the azolium salt with a base. Described herein is a method for the anal. of the NHC present in the reaction flask after the NHC-organocatalyzed reaction. For this, the reaction mixture was treated with elemental sulfur after the reaction and the thus-formed thiourea/thione derivative was isolated. Common NHC-catalyzed transformations such as benzoin reactions, Stetter reactions, homoenolate annulation reactions, and reactions proceeding via the α,β-unsaturated acylazolium intermediate have been studied. The results indicate that after the reactions, 28-84 % of the initial carbenes exist in the free form.
