Synthesis of structurally diverse diarylketones through the diarylmethyl sp3 CH oxidation
摘要:
Under open-flask conditions, an efficient method to assemble a series of diversely functionalized diarylketones in the presence of commercially available NBS has been developed. Yields of up to 99% have been achieved employing diarylmethanes as starting material. Based on O-18-labeled experiment, the addition of stoichiometric water eventually leads to excellent yields in all carbonylation cases. (C) 2014 Elsevier Ltd. All rights reserved.

[EN] Dielectric compositions encompassing one or more poly(arylene ether) polymers are provided. The dielectric compositions have repetitive structural unit (I) where n=0 to 1; m=0 to 1-n; and Y1, Y2, Ar1 and Ar2 are each a divalent arylene radical, Y1 and Y2 derived from biphenol compounds, Ar1 derived from difluoroarylethynes and Ar2 derived from difluoroaryl compounds. Where both Y1 and Y2 are derived from fluorene bisphenol, n=0.1 to 1. Such poly(arylene ether) polymers are employed with a variety of microelectronic devices, for example, integrated circuits and multichip modules. [FR] L'invention concerne des compositions diélectriques comprenant un ou plusieurs polymères de poly(arylène éther). Ces compositions diélectriques renferment le motif de structure répété (I) dans lequel n est égal à 0 ou 1; m est égal à 0 ou 1; et Y1, Y2; Ar1 et Ar2 sont chacun un radical arylène divalent, Y1 et Y2 sont des dérivés de composés bisphénol, Ar1 est un dérivé de difluoroaryléthynes et Ar2 est un dérivé de composés difluoroaryle. Lorsqu'à la fois Y1 et Y2 sont dérivés de fluorène bisphénol, n est compris entre 0,1 et 1. De tels polymères de poly(arylène éther) sont employés dans divers dispositifs microélectroniques, tels que les circuits intégrés et les boîtiers multipuces.
