✦ Synopsis


Photochemical synthesis of biaryls and heterobiaryls from aryl and heteroarylamines, alkylnitrite and aromatic or heteromatic substrates

The photochemical reaction of aromatic and heteroaromatic amines with excess t‐butyl nitrite in aromatic solvents (benzene, p‐xylene, mesitylene) and in hetero‐aromatic solvents (furan, thiophene) leads to biaryls or heterobiaryls. t‐Butyl nitrite is more convenient than isopentyl nitrite which gives by‐products. This new method has been used to synthesize 28 compounds in 17 to 60% yield.
