Abstract

A series of thiaheterocycles were produced by the reaction of diethyl 2,3-dibromomaleate or diethyl 2,3-dibromofumarate with different sulfides without any catalyst. The major products shifted in different conditions. Water was found playing a key role in the generation of carbon–carbon single bonds. Meanwhile, the addition of sulfur could accelerate the reaction and greatly improve the yield of certain products. In addition, unusual, broad single peaks were found in 13C NMR spectra of some compounds. © 2011 Wiley Periodicals, Inc.
