Photoinduced Construction of Thieno[3,4- c ]quinolin-4(5 H )-ones/Selenopheno[3,4- c ]quinolin-4(5 H )-ones Using Diphenyl Disulfide or Diphenyl Diselenide as Sulfur or Selenium Sources.

A photocatalytic synthesis of thieno[3,4- c ]quinolin-4(5 H )-ones/selenopheno[3,4- c ]quinolin-4(5 H )-ones using diphenyl disulfide or diphenyl diselenide as sulfur or selenium sources was developed. Two C-S/Se bonds and one C-C bond were constructed simultaneously without transition metals and other additives.
