Ozawa, Jun published the artcileSilver-Catalyzed C(sp3)-H Chlorination, Name: 2-(Chloromethyl)benzonitrile, the publication is Organic Letters (2017), 19(6), 1430-1433, database is CAplus and MEDLINE.
A silver-catalyzed chlorination of benzylic, tertiary, and secondary C(sp3)-H bonds was developed. The reaction proceeded with as low as 0.2 mol % catalyst loading at room temperature under air atm. with synthetically useful functional group compatibility. The regioselectivity and reactivity tendencies suggest that the chlorination proceeded through a radical pathway, but an intermediate alkylsilver species cannot be ruled out.
Organic Letters published new progress about 612-13-5. 612-13-5 belongs to nitriles-buliding-blocks, auxiliary class Organic Pigment, name is 2-(Chloromethyl)benzonitrile, and the molecular formula is C8H6ClN, Name: 2-(Chloromethyl)benzonitrile.
