Enabled by 1,n (n = 5, 6)-hydrogen atom transfer (HAT), a most prevalent moiety, alkene, as the precursor to an sp3 C-centered radical to promote selective cleavage of inert C(sp3)-H bonds for the generation of azidotrifluoromethylated mols. I [R1 = Me, n-Bu, Ph, etc.; R2 = H, Me, Et, n-octyl; R1R2 = (CH2)3, (CH2)4, (CH2)2O(CH2)2, etc.; X = C(CO2Et)2, C(CH2OBz)2, NTs] was used. Mild conditions, broad scope and excellent regioselective control (>20 : 1) were observed in the reactions. Deuterium labeling studies disclosed the kinetic characteristics of the transformations and verify a direct 1,n-HAT pathway. The key to this C-centered radical relay was that iron played a dual role as a radical initiator and terminator to incorporate the azide functionality through radical oxidation via azido-ligand-transfer. The methods and the later derivatization promised expeditious synthesis of CF3-containing organic azides, γ-lactam and triazoles that were widely used in designing new fluorescent tags and functional materials. In the experiment, the researchers used many compounds, for example, 1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0Application of 14425-64-0).
1-(2-Bromoethyl)-4-methoxybenzene (cas: 14425-64-0) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Application of 14425-64-0
