Hydroxyapatite-supported palladium-catalyzed efficient synthesis of (E)-2-alkene-4-ynecarboxylic esters. Intense fluorescence emission of selected compounds.
A simple procedure for the synthesis of substituted (E)-2-alkene-4-ynecarboxylic esters has been achieved using hydroxyapatite-supported palladium as efficient catalyst surface. The catalyst is recycled, and the turnover number (TON) based on Pd is 16000. A naphthyl-substituted derivative gives very intense fluorescence emission.
