Abstract: A visible-light-photocatalyzed 1,2-arylalkylation of N-(arylsulfonyl)acrylamides with ketone-based dihydroquinazolinones is described. The formal C-C bond cleavage of aliphatic ketones is unified with tandem radical alkylation/1,4-aryl migration/desulfonylation to forge two different types of vicinal C-C bonds and… read more here.

Abstract: High-temperature polycondensation of 4,4′-(hexafluoroisopropylidene)diphenol with the homologous series of bis(fluoroaryl)diketones FArCO[Ar]xCOArF (Ar = 1,4-phenylene, x = 1, 2, 3 or 4) affords polyetherketones [–OArC(CF3)2ArOArCOArxCOAr–]n. The polymers with x = 1–3 are conventional amorphous thermoplastics, but… read more here.
