, p. 508 - 517 (2016)
We demonstrate herein the divergent synthesis of six dyes containing our originally developed rigid and nonplanar donor with three different secondary electron donors (SEDs), namely thiophene, 4-methoxybenzene, and diphenylethene. Evaluation of the photop
A kinetic, product and kinetic isotope effect investigation of the bromination of 1,1-diphenylethyIenes and of their 2,2-dideuterio derivatives

The kinetics of bromination of 1,1-diphenylethylene (1a), 4-trifluoromethyl-1,1-diphenylethylene (1b), and 1-(3-trifluoromethylphenyl)-1-(4-trifluoromethylphenyl)ethylene (1c) and of their 2,2-dideuterio derivatives have been investigated in 1,2-dichloroe

C–H functionalization has provided new opportunities to construct organic molecules in an atom- and step-economic manner, facilitating the derivatization of complex pharmaceutical compounds. However, because of the intrinsically high bond dissociation ene

Fluorescent solid-state organic materials have been intensively researched in recent years. In this study, two 2-(2-hydroxyphenyl)benzothiazole (HBT) derivatives: phenylethylene-modified HBT (HBT-s-Ph) and diphenylethylene-modified HBT (HBT-d-Ph), were sy

A practical method for the dibromination of alkenes without using molecular bromine is consistently appealing in organic synthesis. Herein, we report Mn-catalyzed dibrominated addition and substitution of alkenes only with N-bromosuccinimide, producing a variety of synthetically valuable dibrominated compounds in moderate to high yields. This journal is

Without the use of catalysts and oxidants, a facile and sustainable electrochemical bromination protocol was developed. By introducing the directing groups, the regioselectivity of pyridine derivatives could be controlled at themeta-position utilizing the inexpensive and safe bromine salts at room temperature. A variety of brominated pyridine derivatives were obtained in 28-95% yields, and the reaction could be readily performed at a gram scale. By combining the installation and removing the directing group, the concept ofmeta-bromination of pyridines could be verified.
