A convenient synthesis of a new series of N-aryl-5-(pyridin-3-yl)-1H/3H-1,2,3-triazole-4-carbonitriles and alkyl N-aryl-5-(pyridin-3-yl)-1H/3H-1,2,3-triazole-4-carboxylic acid esters is reported. The newly synthesized 5-(pyridin-3-yl)-1,2,3-triazole derivatives are evaluated for their antibacterial and antifungal activity. Some of these triazole derivatives have exhibited moderate antimicrobial activity.

The known thermal extrusion of Ph3PO from α-acyl-α-ethoxycarbonyl ylides 1 to give acetylenic esters 2 can be accomplished in excellent yield by using flash vacuum (FVP) at 500 deg C.Upon rasing the furnace temperature to 750 deg C, this reaction is accompanied by unexpected loss of the ethoxycarbonyl group to give the terminal alkynes 7 in moderate yield.A mechanism is proposed for this reaction based on isotopic labelling studies.Ten new examples of ylides 1 have been prepared for the first time.
