Synthesis, characterization of metal-free, metallophthalocyanines and catalytic activity of cobalt phthalocyanine in cyclohexene oxidation

Mesoporous Co3O4 as a New Catalyst for Allylic Oxidation of Cyclohexene

“…In the petroleum industry a large amounts of alkane and alkene are produced as by-products which can be oxidized to oxygenated derivatives and converted into value-added products, such as: alcohols, ketones, aldehydes, and carboxylic acids [1].…”

Synthesis, electrochemistry of metal-free, copper, titanium phthalocyanines and investigation of catalytic activity of cobalt, iron phthalocyanines on benzyl alcohol oxidation bearing 4-{2-[3-trifluoromethyl)phenoxy]ethoxy} groups

“…The excess oxidant effects coordination around the ıron and cobalt ion and leads to the generation of inactive intermediate species. [37][38][39][40][41]. This study showed that only 500/1 ratio of oxidant/catalyst was needed for the reaction to get an optimum conversion of benzyl alcohol to reduced products.…”

“…In the 1 H NMR spectrum of the compound 2 the aromatic protons appeared 7.37 and 6.85 ppm, aliphatic group at 4.24 and 4.04 ppm. The 1 H NMR investigation of compound 2 provided the characteristic chemical shifts for the expected structure except for the inner core N-H protons because of the probable strong aggregation of the molecules [31]. The 13 C NMR spectra of the compound indicated 15 carbon atoms at 158.74-66.52 ppm.…”

Novel pthalocyanines bearing 4-ferrocenylphenoxy substituents and their electrochemistry

“…The IR spectra of metal-free 4 and metallophthalocyanines 5, 6 are very similar, except these y (NH) vibrations of the inner phthalocyanine core in the metal-free molecule. The NH protons of compound 4 could not be observed owing to the probable strong aggregation of the molecules [34]. The 1 H NMR spectra of 5 indicated characteristic aromatic protons at 7.72, 7.53, 7.03 ppm and ferrocenyl protons appeared as a singlets at 4.63, 4.33, 4.08 ppm.…”
