Abstract (en)
[origin: WO9640693A1] The present invention is directed to novel vinyl sulfenic acid derivatives, and to a new process for the synthesis of novel vinyl sulfenic acid derivatives. These compounds are useful for the synthesis of benzo[b]thiophenes, in particular 2-aryl-benzo[b]thiophenes.
