microenvironment with ferrocenyl and phenyl groups. The cuprous cluster [Cu2I2(L1)] (C1) was proved to be an effective white light-driven SMP, successfully catalyzing the amination of arylhalides with carbazole. This method showed a diverse substrate scopes of arylhalides with electronical and structural variety, affording the highest yield of 63% for 4-chlorobenzonitrile. X-ray crystallographic, in situ electron
bibenzyls and related ethane derivatives in high yields. Other diselenides were easily caused to cleave to give various aromatic and aliphatic olefins in good yields together with elemental selenium. Lepidopterene, [2.2]paracyclophane, and benzocyclobutene were prepared by thermal cleavage of their corresponding phenylselenomethyl-substituted compounds as an application of the pyrolysis concerned.
The flash vacuum pyrolysis of benzyl phenyl selenides gave bibenzyls and diphenyl diselenide in excellent yields. This type of reaction was successfully applied to the synthesis of the title compounds.
