Visible-Light-Promoted Stereoselective Alkylation by Combining Heterogeneous Photocatalysis with Organocatalysis

Visible-light-promoted stereoselective alkylation by combining heterogeneous photocatalysis with organocatalysis.

The application of sensitizers to utilize visible light for chemical reactions is an established method. Several recent publications have impressively demonstrated the versatile use of visible light for various transformations, such as the conversion of alcohols to alkyl halides, and [2+2], [3+2], and [4+2] cycloadditions as well as carbon– carbon and carbon–heteroatom bond formations. The comb...

Title Heterogeneous visible light photocatalysis for selective organic transformations

Heterogeneous visible light photocatalysis for selective organic transformations.

The future development of chemistry entails environmentally friendly and energy sustainable alternatives for organic transformations. Visible light photocatalysis can address these challenges, as reflected by recent intensive scientific endeavours to this end. This review covers state-of-the-art accomplishments in visible-light-induced selective organic transformations by heterogeneous photocat...

Solar synthesis: prospects in visible light photocatalysis.

Chemists have long aspired to synthesize molecules the way that plants do-using sunlight to facilitate the construction of complex molecular architectures. Nevertheless, the use of visible light in photochemical synthesis is fundamentally challenging because organic molecules tend not to interact with the wavelengths of visible light that are most strongly emitted in the solar spectrum. Recent ...

Visible Light Photocatalysis of 6π Heterocyclization

Photo-mediated 6π cyclization is a valuable method for the formation of fused heterocyclic systems. Here we demonstrate that irradiation of cyclic 2-aryloxyketones with blue LED light in the presence of an IrIII complex leads to efficient and high yielding arylation across a panoply of substrates by energy transfer. 2-Arylthioketones and 2-arylaminoketones also cyclize effectively under these c...
