Chang, Ning-hui published the artcileSynthesis of Substituted Picenes through Pd-Catalyzed Cross-Coupling Reaction/Annulation Sequences and Their Physicochemical Properties, Application In Synthesis of 3032-32-4, the main research area is picene chemoselective preparation; palladium catalyzed Suzuki Miyaura coupling cyclocondensation chloroiodobenzene aralkenylboronate; methoxypicene preparation mol crystal structure.
Picenes I (R = H, Et; R1 = H, MeO; R2 = H, Me3Si; R3 = H, MeO; R4 = H, MeO) were prepared from 1,4-dichloro-2,3-diiodobenzene and alkenyl pinacolboronates II (R = H, Et; R1 = H, MeO; R2 = H, Me3Si; R3 = H, MeO; R4 = H, MeO; BPin = 4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) by palladium-catalyzed Suzuki-Miyaura coupling to give 2,3-bis(arylalkenyl)-1,4-dichlorobenzenes III (R = H, Et; R1 = H, MeO; R2 = H, Me3Si; R3 = H, MeO; R4 = H, MeO) in 38-68% yields followed by palladium-catalyzed cyclization and C-H activation to give I in 23-60% yields. The UV/visible absorption and fluorescence spectra, HOMO and LUMO energies and orbital structures, and oxidation potentials for I were determined; I were p-type semiconductors and were stable to cyclic voltammetry. The structure of I (R = R1 = R2 = R3 = H; R4 = MeO) was determined by X-ray crystallog.
Organic Letters published new progress about C-H bond activation. 3032-32-4 belongs to class chlorides-buliding-blocks, name is 2-Amino-3,6-dichlorobenzoic acid, and the molecular formula is C7H5Cl2NO2, Application In Synthesis of 3032-32-4.
