A novel photoredox-catalyzed direct hydroacylation of
benzylidenemalononitriles
is described. In this method, aroyl chlorides are employed as a readily
available and affordable source of acyl groups, while commercially
available tris(trimethylsilyl)silane acts as both the hydrogen atom
donor and electron donor. By eliminating the requirement for complex
synthesis of acyl precursors and hydrogen atom-transfer (HAT) reagents,
this approach offers a convenient and efficient strategy for the hydroacylation
of benzylidenemalononitriles.
