Ground-breaking progress has been made in the synthesis of chiral cyclic compounds from nonchiral unsaturated substrates with a nucleophilic functionality. A number highly enantioselective electrophilic halocyclizations based on either interaction Lewis acid an substrate or generation intermediate situ electrophile and reagent (see scheme) were developed.
Flexible transparent conductive films (TCFs) are used in a variety of optoelectronic devices. However, their use is limited due to poor thermostability. We report hybrid TCFs incorporation both aluminum-doped zinc oxide (AZO) and silver nanowires (AgNWs). The layered AZO/AgNWs/AZO structure was deposited onto polyimide (PI) substrate displayed excellent When heated 250 °C for 1 h, the change resistivity (Rc) less than 10% (Rc pure AgNW film > 500) while retaining good photoelectric...
Highly flexible AgNW/PI transparent film heaters with superior mechanical and thermal response behavior were fabricated using an all solution-coating method.
[reaction: see text] Optically active pyrazolidine derivatives have been constructed by the Cu- and Pd-catalyzed asymmetric one-pot tandem addition-cyclization reaction of 2-(2',3'-dienyl)-beta-ketoesters, organic halides, dibenzyl azodicarboxylate. The absolute configurations final products depend on structure ligand.
An efficient synthesis of 2,3,4-trisubstituted pyrroles via intermolecular cyclization alkylidenecyclopropyl ketones with amines was observed. The addition anhydrous MgSO4 improved the yields products 3. A possible mechanism involving distal cleavage C-C bond cyclopropane ring proposed.
Abstract A series of polyimide/polytetrafluoroethylene (PI/PTFE) hybrid films were synthesized by blending water‐soluble polyamide acid salts with water‐based PTFE dispersion and thermal imidization to enhance the dielectric proprieties PI. The relationship between filler content properties has been investigated. results showed that PI effectively improved fillers all excellent heat resistance. When addition was 30 wt%, in PI/PTFE‐30 film still good compatibility dispersity. constant loss...
A simple and efficient reaction of CO2 with 2,3-allenamides under mild conditions (CO2 balloon without any metal catalyst in the presence K2CO3 or Cs2CO3) leads to an synthesis 1,3-oxazine-2,4-diones. The high reactivity allene moiety is crucial for success this transformation since corresponding α,β-unsaturated alkenamides alkynamides does not occur.
The highly regioselective PtCl4-catalyzed reaction of indoles with β-allenols in THF at room temperature afforded indole derivatives containing a six-membered ether ring the 3-position moderate isolated yields. On basis D-labeling experiment, mechanistic rationale was proposed.
Bahnbrechende Fortschritte wurden bei der Synthese chiraler cyclischer Verbindungen aus achiralen ungesättigten Substraten mit einem nucleophilen Substituenten erzielt. Hoch enantioselektive elektrophile Halogencyclisierungen, die entweder auf Wechselwirkungen einer chiralen Lewis-Säure Substrat oder In-situ-Bildung eines elektrophilen Intermediats Elektrophil und Reagens beruhen, entwickelt (siehe Schema).
Abstract In this work, poly(thioetherimide) (PTEI) was used to enhance the mechanical properties and thermal stability of an epoxy resin (EP), N , ′, ′‐tetraglycidyl‐4,4′‐diaminodiphenylmethane (TGDDM). The effect PTEI on curing behavior, dynamic mechanical, properties, phase morphology were carefully investigated. addition could improve performances EP, even if only low content added, heat resistance improved, especially for fracture toughness. When 2 wt%, impact strength, toughness,...
