base and Fenton-like reagent treated biomass for Cr(VI) sequestration from aqueous solutions

oegterm

A comparative study of acid, base and Fenton-like reagent treated biomass for Cr(VI) sequestration from aqueous solutions

A wide variety of biomass materials have been used for the removal of toxic chromium(VI) by biosorption. The current study investigated the efficacy of Macadamia nutshells treated with sodium hydroxide, nitric acid, and the Fenton-like reagent in the removal of Cr(VI).
The adsorbents were characterized by FTIR, SEM, TGA, and elemental analysis. Effects of functional parameters influencing the adsorption of Cr(VI), solution pH (pH 1-11), contact time (5-250 min), concentration of adsorbent (1-10 g/L), and adsorbate concentration (10-200 mg/L), were investigated.
The optimum conditions for biosorption were pH 1.4, adsorbent dose of 5 g/L, and 160 min of contact time. In all cases, the base-treated adsorbent displayed superior performance compared to others, with highest percent removal of 98%.
The adsorbate-adsorbent interactions were better explained by the Freundlich isotherm and the pseudo-first-order rate model. The Macadamia-based adsorbents is potentially useful for Cr(VI) removal from aqueous solutions.

Efficient Pd-Catalyzed Direct Coupling of Aryl Chlorides with Alkyllithium Reagents

Organolithium compounds are amongst the most important organometallic reagents and frequently used in difficult metallation reactions. However, their direct use in the formation of C-C bonds is less established.
Although remarkable advances in the coupling of aryl-lithium compounds have been achieved, Csp 2 -Csp 3 coupling reactions are very limited. Here, we report the first general protocol for the coupling or aryl chlorides with alkyllithium reagents.
Palladium catalysts based on y lide-substituted phos phines (YPhos) were found to be excellently suited for this transformation giving high selectivities at room temperature with a variety of aryl chlorides without the need for an additional transmetallation reagent.
This is demonstrated in gram-scale synthesis including building blocks for materials chemistry and pharmaceutical industry. Furthermore, the direct coupling of aryllithiums as well as Grignard reagents with aryl chlorides was also easily accomplished at room temperature.

Cross-linking cellular nucleic acids via a target-directing double click reagent

Bioorthogonal ligation reactions are powerful tools for characterizing DNA metabolism, DNA-protein binding interactions, and they even provide new leads for therapeutic strategies. Nucleoside analogs can deliver bioorthogonal functional groups into chromatin via cellular metabolic pathways, however, insufficient phosphorylation by endogenous kinases often limits the efficiency of their incorporation.
Even when successfully metabolized into biopolymers, steric hindrance of the modified nucleotide by chromatin can inhibit subsequent click reactions. In this chapter, we describe methods that overcome these limitations. Nucleotide monophosphate triesterers can bypass the need for cellular nucleoside kinase activity and thereby enable efficient incorporation of azide groups into cellular DNA.
Steric access to and modification of the azide groups within natively folded chromatin can then be accomplished using a bioorthogonal „intercalating reagent“ comprised of a cationic Sondheimer diyne that reversibly intercalates into duplexes where it undergoes tandem, strain-promoted cross-linking of two azides to give DNA-DNA interstrand crosslinks or DNA-fluorophore conjugation, depending on the relative number and spatial orientation of the azide groups in the DNA.

Polar Isotactic and Syndiotactic Polypropylenes via Organo-zirconium-Catalyzed Masking-Reagent-Free Propylene + Amino-Olefin Copolymerization

Polar functionalized isotactic and syndiotactic polypropylenes (PPs) are synthesized by direct, masking reagent-free propylene + amino-olefin (AO, CH 2 =CH(CH 2 ) x N n Pr 2 , x = 2, 3, 6) copolymerizations using the activated precatalysts rac -[Me 2 Si(indenyl) 2 ]ZrMe 2 and [Me 2 C(Cp)(fluorenyl)]ZrMe 2 , respectively. Polymerization activities at 25 °C are as high as 4208 and 535 kg/(mol·h·atm) with AO incorporation up to 4.0 mol% and 1.6 mol%, respectively.
Remarkably, introducing the amino-olefin comonomers significantly enhances stereoselection for both isotactic ( mmmm : 59.5% → 91.0%) and syndiotactic ( rrrr : 66.3% → 81.3%) products.
