Wu, Dan; Hao, Wen-Juan; Rao, Qian; Lu, Yi; Tu, Shu-Jiang; Jiang, Bo published an article about the compound: 1-(Bromomethyl)-4-iodobenzene( cas:16004-15-2,SMILESS:IC1=CC=C(CBr)C=C1 ).SDS of cas: 16004-15-2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:16004-15-2) through the article.
A new and general photocatalytic Kharasch-type addition/1,5-(SN”)-substitution cascade of 1,7-diynes with alkyl halides such as BrCCl3 and CBr4 was reported for the first time, and used to produce 65 hitherto unreported β-gem-dihalovinyl ketones/aldehydes with moderate to excellent yields in a highly regioselective manner. This reaction tolerates a wide scope of substrates, which offers a green and efficient entry to fabricate synthetically important β-gem-dihalovinyl carbonyl scaffolds. Notably, the late-stage application of these resulting β-gem-dihalovinyl carbonyls shows high and unique reactivity profiles and demonstrates the versatility of their derivatization. Thus, e.g., treatment of diyne I with CBrCl3 under blue irradiation in presence of fac-Ir(ppy)3 and NaOAc base in EtOH afforded II (80%).
