Green synthesis of substituted imidazothiadiazoles using ionic liquid

摘要

An eco-friendly facile synthesis of imidazo[2,1-b]-l,3,4-thiadiazoles is described using ionic liquid,[bmim]PF_6 (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 effective for producing the desired target moiety.
