Research Abstract	A series of 1,3-dialkyltetrazolium-5-olates was prepared from alkyl isothiocyanates and sodium azide, followed by alkylation with dialkyl sulfates. Some of them are liquid with low viscosity at room temperature and can be purified by distillation. 1-Butyl-3-methyltetrazolium-5-olate was converted to the corresponding thiolate and amides, some of which were also found to exist as liquid. The mesoionic liquid serves as a polar solvent for the Mizoroki-Heck reaction and the Miyaura-Suzuki coupling and can be easily recovered and recycled.
