Surface Enhanced Raman Scattering of a Lysosomal Fluorescent Dye
Analysis &Sensing, EarlyView.In this article, the interactions of a lysosomal fluorescent dye with gold nanoparticles are analyzed based on surface‐enhanced Raman scattering (SERS). Their dependence on changes in pH is related to their SERS spectra and to the SERS spectra of the aromatic fragments of the dye.

Chemistry – An Asian Journal, EarlyView.Silyl‐NHC chelate iron complexes with various substituents on NHC were synthesized and demonstrated to be active catalysts for hydroboration and dehydrogenative borylation of olefins. The selectivity of these borylation reactions is significantly controlled by the steric bulk of a substituent on the NHC nitrogen.

Mechanistic evaluations of photocatalytic access to N‐centered radicals and nitrenoids
Bulletin of the Korean Chemical Society, EarlyView.Recently, the photocatalytic formation of reactive N‐centered radicals or nitrenes from prefunctionalized amine precursors via single‐electron transfer (SET) or triplet–triplet energy transfer (TTEnT) has been significantly developed. However, the detailed electron flow during N–X bond cleavage leading to these intermediates remains unclear. Herein, we
