A series of platinum(II) complexes supported by terphenyl diacetylide as well as diimine or bis-N-heterocyclic carbene (NHC) ligands have been prepared. The diacetylide ligands adopt a cis coordination mode featuring non-planar terphenyl moieties as revealed by X-ray crystallographic analyses. The electrochemical, photophysical and photochemical properties of these platinum(II) complexes have been investigated. These platinum(II) diimine complexes show broad emission with peak maxima from 566 nm to 706 nm, with two of them having emission quantum yields >60% and lifetimes 2 μs in solutions at room temperature, whereas the platinum(II) diacetylide complexes having bis-N-heterocyclic carbene instead of diimine ligand display photoluminescence with quantum yields of up to 28% in solutions and excited state lifetimes of up to 62 μs at room temperature. Application studies revealed that one of the complexes can catalyze photoinduced aerobic dehydrogenation of alcohols and alkenes, and a relatively non-toxic water-soluble Pt(II) complex displays anti-angiogenic activity.

Paragraph 0057-0060, (2021/07/31)
The invention relates to a method for catalytically synthesizing an indole derivative by using a ferrous complex, which comprises the following step: by taking arylamine and acetaldehyde as raw materials and a ferrous complex containing a meta-carboboryl methylpyridine structure as a catalyst, conducting reacting at room temperature to prepare the indole derivative. Compared with the prior art, the method utilizes the ferrous complex to efficiently catalyze the reaction of arylamine and acetaldehyde at room temperature to prepare the indole derivative, the reaction condition is mild, the substrate range is wide, and the method has high catalytic activity and yield.

Herein, we report a protocol for desulfonylation of aza-heteroaromatic rings via photoinduced electron transfer and hydrogen atom transfer. This general protocol has a wide substrate range and moderate to good yields. The utility of the method was demonstrated by the chemoselective desulfonylation of a molecule containing both an aliphatic and an aromatic sulfonamide. (Figure presented.).
