Abstract :
An eco-friendly facile synthesis of imidazo[2,1-b]-1,3,4-thiadiazoles is described using ionic liquid,[bmim]PF6 (1-butyl-3-methylimidazolium hexafluorophosphate). The use of recyclable catalyst demonstrates the advantages of significant rate enhancement along with improved yields. The protocol is green and effectivefor producing the desired target moiety.
