Copper phthalocyanine tetrasulfonic acid (CuPcS) as an efficient recyclable catalyst for aromatic nitration using sodium nitrate

Molecular-polaron-coupling-enhanced photocatalytic CO2 reduction on copper phthalocyanine/NiMgFe layered double hydroxide nanocomposites

“…1B). 29 Also, in the Raman spectra (Fig. S5 †) the peaks appearing at 1405 and 1291 cm −1 can be attributed to the vibrations of -N(N-C]N) and -C]C-.…”

Chemo-selective CuPcS catalyzed reduction and esterification of carboxylic acid analogs

“…In systems, there has been an emerging development of the use of solid acids in organic synthesis. 24 To this end, we have developed a new method for the reduction of carboxylic acid by using recyclable solid acids CuPcS and NaBH 4 and secondly, we have developed the esterification of carboxylic acids using CuPcS. The advantages of this new protocol are that the reaction ends in a short period and the catalyst is easily recovered with an excellent yield at moderate to higher temperatures.…”
