Comprehensive Summary An innovative visible‐light‐driven direct hydrogen atom transfer ( d ‐HAT) of Ge–H bond has been developed, wherein the photoexcited 9,10‐phenanthraquinone PC HAT 9 ) serves as an efficient photocatalyst for generation germanium‐centered radicals from germanium hydrides including Ph 3 GeH, n Bu and 2 GeH . By employing hypervalent iodine reagents SOMOphiles, this protocol facilitates streamlined germylation through a mechanism involving germyl radical addition followed by β‐cleavage carboxyl to yield diverse array ethynyl‐, vinyl‐, nitrile‐, phenyl‐functionalized germanes. The methodological leap signifies noteworthy departure previous photocatalytic indirect i relying on combined usage SET with abstractors, which not only advances methodology creating in fashion but also provides access structurally novel pharmaceutically promising organogermanium compounds that are difficult synthesize routine methods.

A direct alkoxycarbonyl radical-induced cascade reaction of 3-aza-1,5-dienes with alkyl chlorooxoacetates is reported. With this approach, an extensive range ester-containing pyrrolin-2-ones are synthesized through photocatalyzed alkoxycarbonylation/cyclization under mild conditions. Moreover, dehydrogenative aromatization can proceed the same photocatalytic system.
