 Title      
 Abstract    The two stereoisomeric a-azidochalkones (1,3-diaryl-2-azidopropenones) are selectively obtain-able, depending on the temperature, by conden-sation of aldehydes with a-azidocarbonyl compounds. For the higher melting point compound the trans configuration is proved by single crystal X-ray analysis of its triphenyl-phosphazeno derivative. Analogous isomers may now be characterised from their X H NMR parameters.
