Facile protection of carbonyl compounds as oxathiolanes and thioacetals promoted by PEG1000-based dicationic acidic ionic liquid as chemoselective and recyclable catalyst
Efficient oxathioacetalization and thioacetalization of carbonyl compounds have been achieved in high yields employing PEG1000-based dicationic acidic ionic liquid as a catalyst. The PEG ionic liquid and toluene have the advantages of both homo

Efficient procedure for oxathioacetalization using the novel ionic liquid
The novel ionic liquid with multi-SO3H groups has been synthesized through the simple procedure and its catalytic activity for the oxathioacetalization was investigated carefully at room temperature under solvent-free condition. The results sho

Facile protection of carbonyl compounds as oxathiolanes and transoxathioacetalization of oxyacetals promoted by iron(III) trifluoroacetate or trifluoromethanesulfonate as chemoselective and recyclable catalysts
Oxathioacetalization of carbonyl compounds and transoxathioacetalization of O,O-acetals/ketals are reported under nearly neutral conditions promoted by iron(III) trifluoroacetate [Fe(CF3CO2)3] or trifluoromethanesulfonate
