在铑催化剂和铜氧化剂存在下，噻吩 - 2 - 甲酰胺与2当量的炔烃进行高效的脱氢环化反应，生成多取代的苯并[c]噻吩。一些合成的苯并[c]噻吩表现出强的固态荧光。
The dehydrogenative annulation of thiophen-2-carboxamides with 2 equiv of alkynes proceeds efficiently in the presence of a rhodium catalyst and a copper oxidant to furnish multiply substituted benzo[c]thiophenes. Some of the synthesized benzo[c]thiophenes exhibited strong solid-state fluorescence.
