  Liquid Triarylamines: The Scope and Limitations of Piers–Rubinsztajn Conditions for Obtaining Triarylamine–Siloxane Hybrid Materials

  摘要：

  New liquid triarylamine-siloxane hybrid materials are produced using the Piers-Rubinsztajn reaction. Under mild conditions, liquid analogues of conventional and commonly crystalline triarylamines are easily synthesized from readily available or accessible intermediates. Using a diverse selection of triarylamines, we explored the effects of siloxane group and substitution pattern on the physical properties of these materials, and we have demonstrated that relatively large molecular liquids with desirable electrochemical properties can be produced. The interactions between the strongly Lewis acidic catalyst used for this transformation, tris(pentafluorophenyl)borane (BCF), and the Lewis basic triarylamine substrates were studied. Through UV-vis-NIR and F-19 NMR spectroscopy, we have proposed that the catalyst undergoes a reversible redox reaction with the substrates to produce a charge transfer complex. The formation of this charge transfer complex is sensitive to the oxidation potential of the triarylamine and can greatly affect the kinetics of the Piers-Rubinsztajn reaction.

• Triarylbismuthane - iodobenzene diacetate: One-pot system for copper-catalysed N-arylation under neutral conditions

  Triarylbismuthanes react with iodobenzene diacetate in dichloromethane under mild, neutral conditions to afford triarylbismuth diacetates, which can be isolated in good yields. The reagents can also be directly used in a one-pot copper-catalysed N-arylation of anilines to give near quantitative yields of the corresponding diarylamines, except in the case of the 2-methoxyphenylbismuth derivative. N-arylation with tris(2-methoxyphenyl)bismuth diacetate was quantitative only when the reaction was performed with the pure isolated reagent. (C) 1998 Elsevier Science Ltd. All rights reserved.
• The Use of Piers–Rubinsztajn Conditions for the Placement of Triarylamines Pendant to Silicone Polymers

  The use of Piers-Rubinsztajn conditions was explored for the synthesis of silicone polymers bearing pendant triarylamine functionality. We have found that up to 60% of the hydride groups of a silicone copolymer can be successfully substituted with a triarylamine moiety, without metathesis or redistribution of the silicone. The resulting polymers are hydrolytically stable. The functionalization procedure is straightforward, conducted under ambient conditions with a simple one-step work-up, and avoids the use of a metal-based catalyst. The resulting phenylated triarylamine-silicone hybrid polymer was characterized by optical absorption and fluorescence spectroscopy, CV, and differential scanning calorimetry. The hybrids maintain the physical appearance of a silicone polymer while adopting the photophysical and electrochemical characteristics of the triarylamine.
