2-Aminobenzaldehyde Chemical Properties,Uses,Production

Description

2-Aminobenzaldehyde is one of the three isomers of aminobenzaldehyde. It is used as a versatile substrate for rhodium-catalyzed alkyne hydroacylation.1 It is used to prepare quinoline derivatives as antiviral agents, electroluminescent materials for OLEDs, and 2-tosylaminopheyl cyclopropylmethanols for gold-catalyzed cyclopropyl carbinol rearrangement. It is also used for the Friedländer-type synthesis, the benzyl C-H bond amination of acrymethylamines catalyzed by hydroxy-TEMPO, and for silver-catalyzed aniline mediated cascade hydroamination/cycloaddition reactions.
