Formula: C8H7BrO2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine, is researched, Molecular C8H7BrO2, CAS is 52287-51-1, about Ortho-directed lithiation of 3,4-(alkylenedioxy)halobenzenes with LDA and LiTMP. The first ortho lithiation of an iodobenzene. Author is Mattson, Ronald J.; Sloan, Charles P.; Lockhart, Christopher C.; Catt, John D.; Gao, Qi; Huang, Stella.
The halo(alkylenedioxy)benzenes I (R = Br, Cl, iodo; R1 = H; X = CH2, CH2CH2, CMe2) underwent rapid regioselective ortho deprotonation upon treatment with LDA or Li-TMP and subsequent reaction with electrophiles, e.g., DMF and Me3SiCl , to give benzene derivatives, e.g., I (R1 = CHO, Me3Si; X = CH2, CH2CH2, CMe2), in 57-94% yields. The mol. structures of I (R , R1, X = Br, CHO, CH2; iodo, CHO, CH2) were confirmed by x-ray crystal structure anal.
This literature about this compound(52287-51-1)Formula: C8H7BrO2has given us a lot of inspiration, and I hope that the research on this compound(6-Bromo-2,3-dihydrobenzo[b][1,4]dioxine) can be further advanced. Maybe we can get more compounds in a similar way.
