, 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

, p. 13621 - 13626 (2020)
The development of molecules with efficient dual-state emission in the red/NIR region is significant for their broader application prospects in the biological field, but still remains a great challenge. Guided by in-depth TDDFT calculations, herein we fir
A kinetic, product and kinetic isotope effect investigation of the bromination of 1,1-diphenylethyIenes and of their 2,2-dideuterio derivatives

A visible-light-mediated radical addition/cyclization tandem reaction for the synthesis of 3-bromomethyl-3,4-dihydroisocoumarins from 2-allylbenzaldehydes and diethyl 2,2-dibromomalonate is described. In this reaction, the bromine radical is generated fro
Light-Promoted Bromine-Radical-Mediated Selective Alkylation and Amination of Unactivated C(sp3)–H Bonds

, p. 1766 - 1776 (2020)
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
Bromination of organic molecules with polymer-supported bromine complexes
Zupan,Segatin
, p. 2617 - 2626 (1994)
Three types of bromine complexes with various polymers bearing basic units (pyridine, piperidine and piperazine) were investigated and the role of polymer matrices on reactivity was tested by three types of organic reactions: electrophilic addition, aroma
A perpendicular phenyl-induced exceedingly efficient solid-state excited state intramolecular proton transfer fluorophore based on 2-(2-hydroxyphenyl)benzothiazole

, p. 365 - 370 (2017)
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.

Aliphatic bromide was used as a halogenation reagent in the presence of DMSO, resulting in 2,2-diarylvinyl bromides from the corresponding 1,1-diarylethylenes. This protocol not only provides a convenient and straightforward strategy for the rapid construction of various 2,2-diarylvinyl bromides without bromine and extra oxidants, but also can improve the atom economy of Kornblum oxidative reaction.
Visible light-mediated metal-free double bond deuteration of substituted phenylalkenes

Various bromophenylalkenes were reductively photodebrominated by using 1,3-dimethyl-2-phenyl-1H-benzo-[d]imidazoline (DMBI) and 9,10-dicyanoanthracene. With deuterated DMBI analogs (the most effective was DMBI-d11), satisfactory to excellent isotopic yields were obtained. DMBI-d11 could also be regenerated from the reaction mixtures with a recovery rate of up to 50%. The combination of the photodebromination reaction with conventional methods for bromoalkene synthesis enables sequential monodeuteration of a double bond without the necessity of a metal catalyst.
