TL;DR: It is shown that the Li-ion battery composed of pyrene-4,5,9,10-tetraone (PYT), which has two six-membered cyclic 1,2-diketone units, exhibits remarkable charge-discharge properties with a high specific capacity of 231 mAh/g, excellent rechargeability, and charge- Discharge ability in the LiNTf(2)/tetraglyme ionic-liquid system.
Journal ArticleDOI
Electrochemical generation of glycosyl triflate pools.
Toshiki Nokami,Akito Shibuya,Hiroaki Tsuyama,Seiji Suga,Albert A. Bowers,David Crich,Jun-ichi Yoshida +6 more
TL;DR: Glycosyl triflates, which serve as important intermediates in glycosylation reactions, were generated and accumulated by the low-temperature electrochemical oxidation of thioglycosides such as thioglucosides, thiogalactoside, and thiomannosides in the presence of tetrabutylammonium triflate (Bu(4)NOTf) as a supporting electrolyte.
Journal ArticleDOI

TL;DR: An iterative method for molecular assembly using (trimethylsilyl)diphenylmethane as a building block based on the cation-pool method to generate dendritic diarylcarbenium ions.
Journal ArticleDOI
Oligosaccharide Synthesis Based on a One-pot Electrochemical Glycosylation–Fmoc Deprotection Sequence
TL;DR: In this paper, Tetrabutylammonium triflate (Bu4NOTf) serves as an effective electrolyte for electrochemical glycosylation using thioglycosides.
