A Red-Emission Fluorescent Probe for Intracellular Biothiols and Hydrogen Sulfide Imaging in Living Cells.

This research centers on the development and synthesis of a longwave fluorescence probe, labeled as , designed for the simultaneous detection of hydrogen sulfide, cysteine/homocysteine, and glutathione. The probe showcases a swift response, good linearity range, and heightened sensitivity, boasting that the detection limits of the probe for Cys, Hcy, GSH and HS were 0.140, 0.

Rapid and General Access to α-Haloketones Using Quaternary Ammonium Salts as Halogen Sources.

A general, rapid, and scalable method for the preparation of α-halogenated ketones using N-alkenoxypyridinium salts as substrates and quaternary ammonium salts as halogen sources was developed, featuring mild reaction conditions, excellent functional group tolerance, short reaction times, and a wide substrate scope.
