In 2022,Liang, Kailun; Wang, Shengchun; Cong, Hengjiang; Lu, Lijun; Lei, Aiwen published an article in CCS Chemistry. The title of the article was 《Electrochemical oxidative [4 + 2] annulation of different styrenes toward the synthesis of 1,2-dihydronaphthalenes》.Recommanded Product: 4316-58-9 The author mentioned the following in the article:
A [4+2] annulation of two different styrenes 3-R-4-R1-5-R2-C6H2C(R3)=CH2 (R = H, Me; R1 = H, Me, Br, Ph, etc.; RR1 = -(CH2)4-, -CH=CH-CH=CH-; R2 = H, Me; R3 = Me, Et, Ph, cyclohexyl, etc.;) and R4CH=CHC6H4-4-OR5 (R4 = Me, Et, propyl; R5 = Me, but-3-en-1-yl, prop-2-yn-1-yl, cyclopentyl, etc.) to construct polysubstituted 1,2-dihydronaphthalenes I was achieved. This transformation proceeded smoothly under electrochem. oxidative conditions without metal catalysts and external oxidants. A series of polysubstituted 1,2-dihydronaphthalenes I was obtained with high regioselectivity and diastereoselectivity. Moreover, polysubstituted 1,2-dihydronaphthalenes I were further transformed to polysubstituted 1,2,3,4-tetrahydronaphthalenes II and polysubstituted naphthalenes III (R5 = Me, Tf), which show great potential in synthetic applications. In the part of experimental materials, we found many familiar compounds, such as Tris(4-bromophenyl)amine(cas: 4316-58-9Recommanded Product: 4316-58-9)
In other references, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)Recommanded Product: 4316-58-9
