Synthesis of dendritic oligo(aryl sulfone)s as supports for synthesis

A m-Terphenyl-Modifed Sulfone Derivative as a Host Material for High-Efficiency Blue and Green Phosphorescent OLEDs

“…BTPS was prepared via a Suzuki coupling reaction of bis(3,5-dichlorophenyl)sulfone with phenylboronic acid using Pd 2 (dba) 3 /PCy 3 /K 3 PO 4 catalyst system in 71% yield. The characterization was established on the basis of 1 H NMR, mass spectrometry, and elemental analysis.…”

Solventless Synthesis of Quaterphenyls and Terphenyls from Chalcones and Allylsulfones under Phase Transfer Catalysis Conditions

“…Moreover, meta-terphenyls have been used as ligands [10], as intermediates for the synthesis of covalent nanostructures [11] and as electron transporting material [12]. For example, 5′,5′′′′-sulfonyl-di-[1,1′:3′,1′′]-terphenyl (BTPS, Scheme 1), bearing two meta-terphenyl subunits, has been recently prepared from bis (3,5-dichlorophenyl)sulfone [13] by Suzuki-Miyaura coupling in order to develop new highly efficient organic light emitting diodes (OLED) [14]. 2 Pd 2 (dba) 3 Although several procedures allow the synthesis of the terphenyl skeleton, the development of alternative methods is still an issue since the regioselective construction of carbon-carbon bonds is a goal not always easy to be achieved.…”
