Synthetic Route of C7H7BrOIn 2021 ,《Visible Light Mediated Photocatalytic N-Radical Cascade Reactivity of γ,δ-Unsaturated N-Arylsulfonylhydrazones: A General Approach to Structurally Diverse Tetrahydropyridazines》 was published in Journal of Organic Chemistry. The article was written by Azzi, Emanuele; Ghigo, Giovanni; Parisotto, Stefano; Pellegrino, Francesco; Priola, Emanuele; Renzi, Polyssena; Deagostino, Annamaria. The article contains the following contents:
The photocatalytic synthesis of different tetrahydropyridazines I (R = H, Me; R1 = Me, Ph; R2 = Me, Ph, naphthalen-2-yl, pyridin-2-yl, etc.), II (Ar = Ph, 4-methylphenyl, 2,4,6-trimethylphenyl; R3 = H, Me), III and (7R)-2-(mesitylsulfonyl)-3,4,4,7-tetramethyl-2,3,4,4a,5,6,7,8-octahydrocinnoline starting from γ,δ-unsaturated N-arylsulfonylhydrazones ArS(O)2NHN=C(R2)CH2C(CH3)(R1)CH=CHR3 were described. Simple structural changes of substrates result into three different pathways beginning from a common N-hydrazonyl radical, which evolves through a domino carboamination/dearomatization, a HAT process, or a photoinduced radical Smiles rearrangement to afford diverse tetrahydropyridazines I, II, III and (7R)-2-(mesitylsulfonyl)-3,4,4,7-tetramethyl-2,3,4,4a,5,6,7,8-octahydrocinnoline. All reactions are carried out in very mild conditions, and the quite inexpensive [Ru(bpy)3]Cl2 is used as the catalyst. Preliminary mechanism studies about luminescence and electrochem. characterization of the involved species are presented. Computational studies allow to rationalize the mechanism in accord with the exptl. findings. In the experimental materials used by the author, we found 1-Bromo-3-methoxybenzene(cas: 2398-37-0Synthetic Route of C7H7BrO)
1-Bromo-3-methoxybenzene(cas: 2398-37-0) can be used in chemical reaction as intermediates to obtain target materials such as dyes, pharmaceuticals, perfumes, photoinitiators and agrochemicals.Synthetic Route of C7H7BrO
