Tuning the electrochemical behavior of organodisulfides in rechargeable lithium batteries using N-containing heterocycles

N-containing heterocycles can tune the electrochemical properties of organodisulfides in lithium batteries. 2,2′-Dipyridyl disulfide exhibits outstanding cycling stability.

An Improved N-Acylation of 1H-Benzotriazole Using 2,2′-Dipyridyl­di­sulfide and Triphenylphosphine

A novel path has been developed for the conversion of carboxylic acids into the corresponding N-acylbenzotriazoles by using 2,2′-dipyridyl disulfide/PPh3 in anhydrous dichloromethane in the presence of 1H-benzotriazole. Mild reaction conditions, short reaction time, easy in handling, wide substrate scope, availability of reagents involved, and moreover avoiding the use of base makes this protocol quite useful for the laboratory practices for N-acylbenzotriazole synthesis.

Facile synthesis of a reduction-responsive amphiphilic triblock polymer via a selective thiol–disulfide exchange reaction

A reduction-responsive amphiphilic triblock polymer was prepared via polycondensation between a dithiol and dipyridyl disulfide, followed by a selective thiol–disulfide exchange reaction.
