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.
Synthesis and Electrochemistry of Pyrimidoquinazoline-5,10-diones. Design of Hydrolytically Stable High Potential Quinones and New Reductive Alkylation Systems

The synthesis of pyrimidoquinazoline-5,10-diones 1 and pyrimidoquinazoline-5,10-diones 2 was carried out in conjunction with the design of both hydrolytically stable high potential quinones and new purine-like reductive alkylators.These systems consist of a benzoquinone ring bearing two fused pyrimidin-4(3H)-one rings.The fused pyrimidinone rings serve to protect 1 and 2 from hydrolysis as well as to raise quinone redox potentials by stabilizing the hydroquinones with internal hydrogen bonds (65 mV increase per hydrogen bond).Synthesis of 1 and 2 involved pyrimidinone ring annelation to a 2,5-diamino-3-nitroterephthalic acid derivative and to a 2,4-diamino-1,5-dicarboxy-3-nitrobenzene derivative, respectively.The synthetic studies provided insights into the electronic effects of nitro and amino groups on the annelation process.
