Cycloaddition des azido - arenes sur l'indene

Co(porphyrin)-catalysed amination of 1,2-dihydronaphthalene derivatives by aryl azides

“…The reaction was run at 75 C with and without Co(TMOP) in a solvent mixture indene/benzene ¼ 1:1. In both cases no azide conversion was observed after 6 h at 75 C. When the two reactions were repeated by using indene as the reaction solvent, the imine N-(1,2-dihydroinden-3-ylidene)-4-nitrobenzenamine (17) [43] was the only isolated aminated compound in approximately 30% yield in both cases. Large amounts of polymeric material was observed due to the well known tendency of indene to polymerise by radical coupling reactions [36] (Scheme 10).…”
