It is named after Howard Ensign Simmons, Jr. and Ronald D. Smith. The Application of the Schmidt Reaction and Beckmann Rearrangement to the Synthesis of Bicyclic Lactams: Some Mechanistic Considerations. Australian Journal of Chemistry 2010, 63 (2) , 211. The Claisen-Schmidt reaction (cross-Aldol reaction) is a condensation reaction of aldehydes and carbonyl compounds leading to β-hydroxycarbonyl compounds and has been playing an important role in Schmidt reaction 117). S n 1 substitution is also highly probable in the reaction of α-halo ethers and sulfides with azide ions.
The mechanism has not been fully clarified, but pure carbenes … Schmidt Reaction. The acid-catalysed reaction of hydrogen azide with electrophiles, such as carbonyl compounds, tertiary alcohols or alkenes. After a rearrangement and extrusion of N 2, amines, nitriles, amides or imines are produced. The Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually a aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen. It is named after Karl Friedrich Schmidt (1887–1971), who first reported it in 1924 by successfully converting benzophenone The condensation of an aromatic aldehyde with an aliphatic aldehyde or ketone in the presence of a base or an acid to form an α,β‐unsaturated aldehyde or ketone with high chemoselectivity is generally known as Claisen–Schmidt condensation.

His supervisor has been Umeå University (UmU) researcher Florian Schmidt, PI on Bio4Energy Thermochemical Conversion Technologies.
This reaction has been applied to the preparation of chalcone, flavanone, 1,3‐diarylpropane derivatives, and a new family of macrocycles in a single step. This condensation is found to be accelerated by microwave activation either in a polar solvent (e.g., H 2 O) or without solvent, starting from aldehydes or by means of acetals.

[1] [2] [3] It is an example of a radical-nucleophilic aromatic substitution. The reaction of Claisen-Schmidt to obtain chalcones has similarly been previously reported via the applying of specific catalysts, KF-Al 2 O 3 , or 2-2-bipyridine complex to {Co (OAc) 2 } were

In 1881 he published a seminal paper on what would become known as the Claisen-Schmidt reaction, a crossed aldol condensation.
