To overcome the low-energy-density limitation of supercapacitors, we aimed to achieve a material with a high specific capacitance by manipulating the nanostructure of FeS 2 , which comprises the most abundant and affordable elements. In this study, nanosheet-assembled FeS 2 (NSA-FeS 2 ) was fabricated using a novel method. Sub-micron droplets of sulfur particles stabilized with polyvinylpyrrolidone were formed in silicone oil medium, and Fe(CO) 5 was absorbed and reacted on the surface to form core-shell particles, ES/[Fe], with a sulfur core and an iron-containing outer shell. The high temperature treatment of ES/[Fe] produced NSA-FeS 2 , in which pyrite FeS 2 nanosheets grew and were partially interconnected. In a three-electrode system, the as-prepared NSA-FeS 2 and NSA-FeS 2 /polyaniline (PANI) composites exhibited specific capacitances of 763 and 976 Fg -1 , respectively, at a current density of 0.5 Ag -1 , with corresponding capacitance retentions of 93 and 96% after 3000 charge-discharge cycles. The capacitance retention of the NSA-FeS 2 /PANI composites was 49% when the current density was increased from 0.5 to 5 Ag -1 . Notably, the obtained specific capacitances exhibited the highest values in pure FeS 2 and FeS 2 -based composites, indicating the significant potential for the utilization of iron sulfide in pseudocapacitive electrode materials.

Decarboxylative coupling of sp-sp2 carbons is possible by palladium catalyst. Employing propiolic acid (1) as a difunctional alkyne, and using the consecutive reactions of the Sonogashira reaction and the decarboxylative coupling, unsymmetrically substituted diaryl alkynes were obtained in moderate to good yield.

The nickel and phosphite catalytic system with sodium methoxide enables a very efficient aminocarbonylation reaction to be performed between aryl iodides or bromides and N,N-dimethylformamide (DMF). Phosphite ligand 1, which is very stable to air and moisture and, furthermore, inexpensive, afforded the highest reaction yield.
