Abstract

The Pd-TPPTS complex (TPPTS - trisodium salt of 3,3′,3′′-phosphanetriyl benzenesulfonic acid) and PdCl42− salt heterogenised onto Zn2AlNO3 layered double hydroxide (LDH) using an ion-exchange procedure, have been shown to be efficient green catalysts in the cycloisomerisation reaction of acetylenic carboxylic acids to the corresponding 5-membered heterocycles.
