摘要：
Acidic ionic liquid butyl ethyl phenyl selenonium tetrafluoroborate, [BEPSe]BF4, was successfully employed as a catalyst for the synthesis of several dithioacetals in the absence of a solvent. The method is general and selectively afforded thioacetals derived from aldehydes and ketones in good yields. (c) 2008 Elsevier Ltd. All rights reserved.
