Novel one-pot synthesis of 1,2,4-triazolidin-3-thiones comprising piperidine moiety |
||
| Abstract: | Abstract A simple synthetic strategy for the synthesis of piperidinyl spiro-1,2,4-triazolidin-3-thiones 11–15 is proposed, exploiting microwave activation coupled with solvent-free reaction conditions catalyzed by NaHSO4.SiO2 heterogeneous catalyst is described. | |
