The reaction of cyclopropenethiones and electron-deficient alkynes has been described in this context. The corresponding thioethers and thiocyclobutanones were afforded depending on the reaction conditions and the employed substrates. Ambient water participated in the reaction on the basis of deuterium labeling experiment. In the plausible reaction mechanism, we propose that the reaction might proceed...
Multivalent lactose (Lac-QDs)- and galactose (Gal-QDs)- coated CdSeS-ZnS core-shell quantum dots (QDs) were prepared. The formula of the glyco-QDs was determined by nuclear magnetic resonance (NMR) and inductively coupled plasma-optical emission spectrometry (ICP-OES). The uptake of the Gal-containing glyco-QDs by HepG2 cells was investigated. Flow cytometry (FCM) and fluorescence microscopy analysis...
