Sequential activation of a-bonds : Intermolecular cascade annulation with migration and remote functionalization

We demonstrate a new catalytic property of the lanthanide compound CeCl3 center dot 7H(2)O which sequentially activates N-H, sp(2) C-H and sp(3) C-H sigma-bonds at ambient temperature. The powerful catalyst enables selective C-C and C-N bond-forming intermolecular cascade annulation between enamines and diary1-1,2-diketone to afford functionalized 3,3-diaryl-3-pyrrolin-2-ones involving migration of an aromatic ring. We have also initiated a new multicomponent strategy utilizing readily available and inexpensive precursors and environmentally benign CeCl3 center dot 7H(2)O as an efficient catalyst under benign reaction conditions towards direct synthesis of several N-heterocycles including pentasubstituted 2-pyrrolinones and pyrroles. These observations provide new prospects and perspectives in sigma-bond activation process for easy access to functional molecules.

New applications of N-acyliminium precursors: Tetracarbonyliron-mediated stereoselective alkylations of 5-(R)-isopropoxy-3-pyrrolin-2-ones

Lewis acid catalyzed allylic substitutions with several nucleophiles at C-5 of the cis-tetracarbonyliron complexes of N-acetyl- and N-tosyl-5-(R) -isopropoxy-3-pyrrolin-2-ones occur highly regio- and stereoselectively.

Simultaneous enhancement of dielectric and mechanical properties ofhigh-density polyethylene/nitrile rubber/multiwalled carbon nanotubecomposites prepared by dynamic vulcanization

Polymer dielectric composites, which possess high dielectric and loss suppression with excellent mechanical properties, are of crucial importance in practical applications. Herein, high-density polyethylene/nitrile rubber/multiwalled carbon nanotube (HDPE/NBR/MWCNT) composites were fabricated by the dynamic vulcanization (DV) technique. The effect of DV on the structure and properties of HDPE/NBR/MWCNTs was systematically investigated. The results illustrate that the DV technique combines the advantages of the crosslinked phase and melt processability of thermoplastics. With the increase of dicumyl peroxide content, the dielectric permittivity and the mechanical properties clearly increase, due to a better compatibility and dispersibility achieved by DV. More importantly, a continuous decrease of dielectric loss and conductivity are observed with the increase of dicumyl peroxide content. These can probably be assigned to the combination of better dispersion and slower chain mobility of the NBR phase induced by crosslinking. (c) 2020 Society of Industrial Chemistry

Polytriphenylamine Derivative and Carbon Nanotubes as Cathode Materials for High-Performance Polymer-Based Batteries

Composites of polytriphenylamine (PTPA), its novel derivative poly(4-carbamoyl-N,N-diphenylaniline-2,2,5,5-tetramethyl-pyrrolin-1-oxyl) (PTPA-PO), and multi-walled carbon nanotubes (CNTs) were synthesized by in situ polymerization. The characterization results showed that the CNTs were homogeneously distributed in the polymer matrix and formed a cross-linked conductive network. The electrical properties of PTPA/CNT composites were better than those of traditional acetylene black as conductive agents. Electrochemical tests showed that the initial specific discharge capacity of the PTPA/CNT composites was 107.6 mAh g(-1 )(theoretical capacity of PTPA is 109 mAh g(-1)). Furthermore, further research to increase the specific capacity demonstrated that the as-synthesized polytriphenylamine derivative, PTPA-PO, with a CNT cathode presented two well-defined plateaus and an enhanced discharge capacity of 139.3 mAh g(-1). Additionally, the PTPA-PO/CNT electrode showed superior cycling performance and remained above 90% of the initial capacity after 100 cycles. The enhanced electrochemical performance of PTPA-PO was due to its combination of the conducting polymer PTPA and free radical active site pendant PO, which increased its electrochemical reaction rate, and this composite is a promising material for high-performance polymer-based organic batteries.

One-Pot Synthesis of B-Aryl Carboranes with Sensitive Functional Groups Using Sequential Cobalt- and Palladium-Catalyzed Reactions

The simple and efficient method was developed for the one-pot synthesis of B-substituted aryl derivatives of ortho-carborane with functional groups sensitive to organolithium and organomagnesium reagents using 9-iodo-ortho-carborane and generated in situ organozinc compounds. The method proposed was used to prepare a series of 9-aryl-ortho-carboranes, including those containing nitrile and ester groups, 9-RC6H4-1,2-C2B10H11 (R = p-Me, p-NMe2, p-OCH2OMe, o-OMe, p-OMe, o-CN, p-CN, o-COOEt, m-COOEt, and p-COOEt). It was demonstrated that the same approach can be used for synthesis of diaryl derivatives of ortho-carborane 9,12-(RC6H4)(2)-1,2-C2B10H10 (R = H, p-Me). The solid-state structures of 9-RC6H4-1,2-C2B10H11 (R = p-NMe2, p-OCH2OMe, o-OMe, o-CN, p-CN, m-COOEt, and p-COOEt) and 9,12-(p-MeC6H4)(2)-1,2-C2B10H10 were determined by single crystal X-ray diffraction.
