Straightforward preparation of highly loaded MWCNT–polyamine hybrids and their application in catalysis

Abstract

Multiwalled carbon nanotubes (MWCNTs) were easily and efficiently functionalised with highly cross-linked polyamines. The radical polymerisation of two bis‐vinylimidazolium salts in the presence of pristine MWCNTs and azobisisobutyronitrile (AIBN) as...

Novel copolymers of vinyl acetate. 4. Halogen ring-substituted ethyl 2-cyano-3-phenyl-2-propenoates

“…2-Br, 2,2,2,3,2,4-dimethoxy-substituted benzaldehydes, ethyl cyanoacetate, piperidine, vinyl acetate, 1,1'-azobiscyclohexanecarbonitrile, (ABCN), and toluene supplied from Sigma-Aldrich Co., were used as received. Instrumentation is described in [19].…”

“…Halogen ring-substituted ethyl 2-cyano-3-phenyl-2propenoates (HECP) offer a convenient way to introduce a variety of functional groups in polyvinyl acetate backbone. 2-Bromo HECP is reported in preparation of highly loaded MWCNT-polyamine hybrids and their application in catalysis [1], as well as in synthesis of thiazacridine derivatives as anticancer agents against breast and hematopoietic neoplastic cells [2]. 3-Bromo HECP is involved in synthesis of novel selenophenes from activated acetylenes, ethyl 2-cyano-3-arylacrylate and potassium selenocyanate [3], also in straightforward preparation of highly loaded MWCNT-polyamine hybrids and their application in catalysis [4].…”

Synthesis and styrene copolymerization of novel halogen ring-monosubstituted tert-butyl phenylcyanoacrylates

“…4-Bromo ring-substituted ethyl phenylcyanoacrylate (PCA) is reported in vitro, molecular docking, and ADME study of uracil derivatives as potential anticancer agents [1]; in synthesis of novel selenophenes from activated acetylenes, such as ethyl 2-cyano-3-arylacrylate and potassium selenocyanate [2]; in Knoevenagel condensation in the presence of polyoxomolybdates as efficient catalysts [3]; in preparation of highly loaded MWCNT-polyamine hybrids and their application in catalysis [4]; in catalysis studies on precise control of the oriented layered double hydroxide nanosheets growth on graphene oxides leading to efficient catalysts for cascade reactions [5], and in synthesis of arylidene derivatives by microwave assisted NH4OAc catalyzed under solvent free condition [6]. 4-Chloro ring-substituted 1,1-dimethylethyl PCA is mentioned in mechanistic studies of copper-catalyzed 1,4-addition of organoboronates to alkylidene cyanoacetates [7], and in synthesis of β-(arylmethylene)-α-cyano-2-alkenoic acid ethyl ester derivatives via Knoevenagel condensation of aryl aldehydes with cyanoacetic acid methyl ester and subsequent transesterification [8].…”

A Study on the Stability of Carbon Nanoforms–Polyimidazolium Network Hybrids in the Conversion of CO2 into Cyclic Carbonates: Increase in Catalytic Activity after Reuse

“…In addition to non-covalent interactions, other studies show how different organic polymers roll up along the shape of the nanotube, as a result of an in situ radical polymerization [ 23 , 24 ]. Recently, we have exploited the well-known high affinity between ionic liquids (ILs) and CNFs [ 25 ] by functionalizing CNTs and CNHs with imidazolium salt-based polymers, which perfectly covered the whole surface of the carbonaceous skeletons [ 26 , 27 , 28 ]. Among the numerous applications of ILs, their use for the uptake of CO 2 and its conversion has aroused a great interest in the scientific community [ 29 , 30 ].…”
