Cascade C(sp<sup>3</sup>)–S Bond Cleavage and Imidoyl C–S Formation: Radical Cyclization of 2‑Isocyanoaryl Thioethers toward 2‑Substituted Benzothiazoles
A cascade
radical cyclization of 2-isocyanoaryl thioethers with <i>H</i>-phosphorus oxides, organoboronic acids, or alkyl radical
precursors has been efficiently developed, providing a novel and highly
efficient methodology to structurally diverse C2-substituted benzothiazole
derivatives with broad functional group tolerance and good yields.
This cascade radical process achieves the first cycloaddition of an
imidoyl radical from isocyanide to sulfur atom, rending CÂ(sp<sup>2</sup>)–S bond formation
Mechanical Activation of Platinum–Acetylide Complex for Olefin Hydrosilylation
Harnessing mechanical forces to activate
latent catalysts has emerged
as a novel approach to control the catalytic reactions in organic
syntheses and polymerization processes. However, using polymer mechanochemistry
to activate platinum-based catalysts, a class of important organometallic
catalysts in industry, has not been demonstrated so far. Here we show
that the platinum–acetylide complex is mechanoresponsive and
can be incorporated into a polymer backbone to form a new mechanophore.
The mechanically induced chain scission was demonstrated to be able
to release catalytically active platinum species which could catalyze
the olefin hydrosilylation process. Various control experiments were
conducted to confirm that the chain scission and catalytic reaction
were originated from the ultrasound-induced dissociation of platinum–acetylide
complex. This work further exemplifies the utilization of organometallic
complexes in design and synthesis of latent catalysts for mechanocatalysis
and development of self-healing materials based on silicone polymers
Indoor particle bounce reductions rates using mineral-oil-spread agar plate in replace of agar plate; the particle concentration levels were monitored using an optical particle counter; data points represent averages and standard deviations of 20 min continuous data; a negative value suggests an increase in particle bounce.

Isolation and purification of polysaccharides.
<p>(A) Ion exchange chromatogram of TPPPS on DEAE-cellulose column, eluted with distilled water, 0.01, 0.03, 0.05, 0.1, and 0.3 M NaCl. T1: TPPPS1; T2: TPPPS2; T3: TPPPS3. (B, C, and D) Gel filtration chromatogram of TPPPS1, TPPPS2, and TPPPS3, respectively, on Sephadex G-200 column eluted with 0.1 M NaCl.</p
Effects of TPPPS1-3 and TPPPS on antiviral activity <i>in vitro</i>.
<p>(A) DF1 cells cultured in 24-well plates were infected with 10 μL/well (TCID<sub>50</sub> of 10<sup>3.75</sup>/0.1 mL) ALV-B. After 9 d of culture in MM containing different concentrations of TPPPS or TPPPS1-3, viral titers in the supernatant were directly determined by TCID<sub>50</sub> assays on DF1 cells. PBS treatment wells served as the control. All values shown are presented as means ± SD from three independent experiments. An asterisk indicates that the value of the corresponding group was significantly different from that of the control group (<i>P</i> < 0.05, ANOVA). (B) DF1 cells infected with ALV-B were treated with 50 μg/mL of TPPPS3 at different viral infection periods, and viral titers in the supernatant were directly determined by TCID<sub>50</sub> assays on DF1 cells. Ad is defined as the “adsorption” period; AA is defined as the period “after adsorption”; Al is the period wherein the polysaccharide was always present. PBS treatment wells served as the control. All values shown are presented as means ± SD from three independent experiments. Different superscripts indicate a significant difference (<i>P</i> < 0.05).</p
