A new configuration of the solid-state battery : Magnesium|polymer proton conductor|gold, based on the use of poly(o-methoxyaniline)
Synthetic Metals, 1997Co-Authors: W.a. Gazotti, G. Casalbore-miceli, N. Camaioni, Marco A. De Paoli, A.m. FicheraAbstract:Abstract A solid-state battery was constructed by interfacing a pressed pellet of poly ( o -methoxyaniline), in the emeraldine form with p -toluene sulfonic acid as doping agent, to a Magnesium electrode covered with a film of Magnesium Perchlorate; the contact on the poly ( o -methoxyaniline) was done by means of a gold electrode. The so-obtained cell, Mg ¦ Magnesium Perchlorate ¦ poly ( o -methoxyaniline) ¦ gold, was able to supply energy with a power depending on discharge current and on environmental humidity. Values of power up to 2.5 mW cm −2 at discharge currents of about 2 mA cm −2 were reached.

stereoselective synthesis of amino substituted cyclopentafullerenes promoted by Magnesium Perchlorate ferric Perchlorate
Organic and Biomolecular Chemistry, 2020Co-Authors: Kun Wang, Huijuan Wang, Fabao Li, Cheng Huang, Abdullah M AsiriAbstract:A facile one-step reaction of [60]fullerene with cinnamaldehydes and amines promoted by Magnesium Perchlorate/ferric Perchlorate under air conditions afforded a series of rare amino-substituted cyclopentafullerenes in moderate to good yields. Stereoselectivity was readily achieved. Secondary amines exclusively produced N,N-disubstituted cyclopentafullerenes as cis isomers, while arylamines gave N-monosubstituted cyclopentafullerenes with a preference of cis isomers as major products. N-Monosubstituted cyclopentafullerenes could be further converted into other scarce cyclopentafullerenes in the presence of acid chloride or paraformaldehyde. A possible reaction pathway was proposed to elucidate the formation of amino-substituted cyclopentafullerenes.

facile access to 2 5 diaryl fulleropyrrolidines Magnesium Perchlorate mediated reaction of 60 fullerene with arylmethylamines and aryl aldehydes
RSC Advances, 2016Co-Authors: Hongyu Zhang, Huijuan Wang, Fabao Li, Xiaofeng ZhangAbstract:The facile one-step reaction of [60]fullerene with arylmethanamines and aryl aldehydes in the presence of Magnesium Perchlorate under air conditions generated a series of scarce 2,5-diaryl fulleropyrrolidines in good to excellent yields. Intriguingly, all the formed 2,5-diaryl fulleropyrrolidines were confirmed only as cis isomers and thus displayed high stereoselectivity. In addition, the type of aryl aldehyde was found to have a great correlation with the formation of different 2,5-diaryl fulleropyrrolidines. Aryl aldehydes without electron-withdrawing groups always afforded exclusively the desired 2,5-diaryl fulleropyrrolidines, while aryl aldehydes connecting electron-withdrawing groups unexpectedly produced symmetrical 2,5-diaryl fulleropyrrolidines besides the anticipated fulleropyrrolidines. A plausible formation mechanism for the 2,5-diaryl fulleropyrrolidines was proposed.
