A general and efficient photocatalytic annulation-carbohalogenation of 1,7-enynes with a wide variety of alkyl halides were reported, which resulted in atom-economic synthesis of functionalized 3,4-dihydronaphthalen-1(2H)-ones with good yields and high stereoselectivity under the mild and oxidant-free conditions. The reaction demonstrated remarkable compatibility regarding alkyl halides as a bifunctional reagents, such as ethyl-2-bromo-2,2-difluoroacetate, ethyl-2,2-difluoro-2-iodoacetate, perfluorobutyl iodide, bromotrichloromethane, and diethyl-2-bromomalonate, and which provided wide substrate scope, high functional group tolerance, and 100% atom utilization.fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Reference of fac-Tris(2-phenylpyridine)iridium) was used in this study.
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Reference of fac-Tris(2-phenylpyridine)iridium
