A series of palladium(II)–porphyrin complexes that display dual emissions with lifetimes up to 437 μs have been synthesized. Among the four complexes, PdF20TPP is an efficient and robust catalyst for photoinduced oxidativeCHfunctionalization by using oxygen as terminal oxidant. α‐Functionalized tertiary amines were obtained in good to excellent yields by light irradiation (λ>400 nm) of a mixture

A family of quinoline–platinum(II) complexes as efficient photocatalysts is presented. Their key characteristic is their easy preparation by coordination of the readily available 8-hydroxy- or 8-thio-quinoline ligands, which are well known for their strong chelating ability to different metal ions. In the different photochemicaltransformations investigated, such as cross-dehydrogenative coupling,

Two-dimensional covalentorganic frameworks (2D-COFs) are excellent candidates for photocatalytic organictransformations due to their periodic columnar π-arrays and ordered nanochannels. Here, we present a novel 2D-COF that features permanent porosity with high surface area and large pore volume, and exhibits a high crystallinity and an excellent stability. Indeed, the new 2D-COF was found to be a
In this communication we describe the oxidativeCCbondformation of tertiary amines with various nucleophiles under very mild and environmental friendly conditions by using mesoporous graphitic carbon nitride (mpg‐C3N4) semiconductor as a heterogeneous, metal‐free photosensitizer in combination with visiblelight and oxygen as the terminal oxidation agent. This system can be further combined with
在本通讯中,我们通过使用介孔石墨碳氮化碳(mpg-C 3 N 4)半导体作为非均相,无金属的光敏剂组合,描述了在非常温和且环境友好的条件下叔胺与各种亲核试剂的氧化CC键形成用可见光和氧气作为终端氧化剂。该系统可以进一步与脯氨酸-有机催化结合使用,以实现氧化串联光催化,这证明了当前光合作用系统的丰富化学可能性。
