and thioacetalization of carbonylcompounds 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 homogeneous and heterogeneous phases at different temperatures (biphasic conditions at lower temperatures and monophasic at higher temperatures) with the ease of product as well as catalyst separation
