Additionally, an electricity on/off study revealed that any chain processes were transient and short-lived (Fig. 6D). This finding suggested that electrolysis is required for sustained product formation, indicating that the reaction was less likely to proceed through a radical chain mechanism. Fig....
In more detail, Schwartz notes that only one of several possible chemical reactions takes place when N-monoalkylglucamines are condensed with fatty esters or oils. The reaction is said to give compounds formulated as amides, e.g., ##STR1## where R2 is fatty alkyl and R1 is a short-chai...

Versions Notes Abstract The recent developments in asymmetric A3(aldehyde–alkyne–amine) coupling has been summarized in this review. Several interesting modifications of the ligands enabled the highly enantioselective synthesis of chiral propargylamines, which are further used in the construction of nitrog...

Versions Notes Abstract A significant increase of microbial resistance to glycopeptides (especially vancomycin-resistant enterococci andStaphylococcus aureus) prompted researchers to design new semisynthetic glycopeptide derivatives, such as dual-action antibiotics that contain a glycopeptide molecule and an antiba...
We can exclude that the shift of the band is associated with the concentration quenching effects, since the excitation at the short wavelength side of the emission band (e.g., at 480 nm) still contributes to an intense emission, being even higher for high-doped films than for low-doped ...
