Chiral spirocyclic-amide-derived triazolium salts were used as new phase-transfer organocatalysts for asymmetric alkylation to construct 2,5-diketopiperazine motifs containing one or two tetrasubstituted carbon centers in high yields with excellent cis-diastereoselectivity and enantioselectivity. Control experiments and DFT calculations revealed the possible reaction mechanism and the origins of the

A viologen compound is a crystalline compound including a heterocyclic moiety in which a carboxylate of an alkali metal is bound directly or indirectly to both ends of a basic skeleton containing 4,4□-bipyridinium and an anionic moiety that pairs with 4,4□-bipyridinium. The viologen compound can be used, for example, as a negative electrode active material for an electricity storage device including a negative electrode containing the negative electrode active material, a positive electrode containing a positive electrode active material capable of giving and receiving anions, and an ion-conducting medium that is disposed between the positive electrode and the negative electrode and conducts anions.
