Synthesis of substituted Se-phenyl selenocarboxylates from terminal alkynes
Se-Phenyl selenocarboxylates have been conveniently prepared from (phenylseleno)acetylenes by treatment with p-toluenesulfonic acid monohydrate in dichloromethane. This easy conversion is compatible with a broad range of oxygen- and nitrogen-containing functional groups. The Se-phenyl selenocarboxylates were easily converted into the corresponding esters and amides. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
