Abstract

The reaction of  2-thiophenecarbaldehyde  with  arene diazonium chlorides  in the presence of CuCl2 catalyst gave 5-aryl-2-thiophenecarbaldehydes.  Use of 4-nitrobenzene diazonium chloride in the reaction also gave the isomeric 3-(4-nitrophenyl)-2-thiophenecarbaldehyde. Condensation products of the 5-aryl-2-thiophenecarbaldehydes with cyanoacetic acid esters, cyanoacetamide, and with barbituric and dimethylbarbituric acids were prepared.
