Nitrene insertion into an adjacent o-methoxy group followed by nucleophilic addition to the heterocumulene intermediate: Experimental and computational studies

The chemistry of aryl azides and aryl nitrenes is rich and varied in nature with different products being obtained with minor changes in reaction conditions. Thermolysis of azido- dimethylsuccinylosuccinate has been carried out to study the behaviour of t

A Covalent and Modular Synthesis of Homo- And Hetero[ n]rotaxanes

Incorporation of 2,5-dihydroxyterephthalate as a covalent scaffold in the axis of a 30-membered all-carbon macrocycle provides access to a modular series of rotaxanes. Installment of tethered alkynes or azides onto the terephthalic phenolic hydroxyl functionalities, which are situated at opposite sides of the macrocycle, gives versatile prerotaxane building blocks. The corresponding [2]rotaxanes are obtained by introduction of bulky stoppering ("capping") units at the tethers and subsequent cleavage of the covalent ring/thread ester linkages. Extension of this strategy via coupling of two prerotaxanes bearing complementary linker functionalities (i.e., azide and alkyne) and follow-up attachment of stopper groups provide efficient access to [n]rotaxanes. The applicability and modular nature of this novel approach were demonstrated by the synthesis of a series of [2]-, [3]-, and [4]rotaxanes. Furthermore, it is shown that the prerotaxanes allow late-stage functionalization of the ring fragment introducing further structural diversity.

Substituent effect on redox potential of terephthalate-based electrode materials for lithium batteries

The substituent effect on the redox potential of lithium terephthalate was studied using symmetrical dilithium disubstituted-terephthalates incorporating bromo, methoxy and amino groups. All the terephthalate derivatives have been synthesized and evaluated as anode material for lithium-ion batteries. The electrochemical results revealed an increase in the reduction potential in the case of bromo and methoxy groups and almost the same in the case of amino group compared to unmodified dilithium terephthalate. In addition, a very first tendency between the 13C chemical shifts and FTIR signal of the carbonyl and the reduction potential of the studied disubstituted-terephthalates was formulated.
