As an extension of the successful dicyanopyrazine photoredox catalysts, a series of X-shaped push-pull mols. with a systematically altered structure I [R1 = SMe, CN, 2-thienyl, etc.; R2 = OMe, CN, 2-thienylsulfanyl, etc.; R3 = SMe, CN, 2-thienylsulfanyl, etc.] were designed and facilely synthesized and their structure-property relationship was elucidated in detail via exptl. as well as theor. calculations Dicyanopyrazines I were proven to be powerful photoredox catalysts with a push-pull arrangement that allowed facile property tuning by interchanging a particular part of the D-π-A system. Changing the mutual position of the cyano acceptors and the methoxy, methylthio and thienyl donors as well as modifying the linker allowed wide tuning of the fundamental properties of the catalysts. Contrary to the currently available organic photoredox catalysts, a series of catalysts based on a pyrazine heterocyclic scaffold with easy synthesis and further modification, diverse photoredox characteristics and wide application potential across modern photoredox transformations was provided . The photoredox catalytic activities of the target catalysts were examined in a benchmark cross-dehydrogenative coupling and novel and challenging annulation reactions.
