Microwave heating was used to synthesise different types of 1, 2, 3 triazolium based ionic liquids (5a-j) with good yield in reduced time. These ionic liquids were further screened as reaction medium for Aldol reaction using two different most promising organocatalysts; proline and proline tetrazole. In both cases, Aldol products were obtained in good yield and selectivity with each ionic liquid. It is important to notify that all the ionic liquids (5a-j) offer 5 times recyclability with our catalytic system (Proline or Proline tetrazole).
