Robert Gerdes,Dieter Wöhrle,Wolfgang Spiller,Gerhard Schneider,Günter Schnurpfeil,Günter Schulz-Ekloff +5 more
TL;DR: In this paper, the photo-oxidation of phenol and 2-, 3- and 4-monochlorophenols by irradiation with visible light in aqueous alkaline solution in the presence of photosensitizers and oxygen is described.
Journal ArticleDOI
Efficient oxidations and photooxidations with molecular oxygen using metal phthalocyanines as catalysts and photocatalysts
Dieter Wöhrle,Olga Suvorova,Robert Gerdes,Oliver Bartels,Lukasz Lapok,Natalia Baziakina,Serguei Makarov,Aneta Slodek +7 more
TL;DR: In this article, different types of soluble low molecular weight or oligomeric and insoluble heterogeneous catalysts and photocatalysts were developed for photooxidation reactions using molecular oxygen as oxidant.
Journal ArticleDOI
Photooxidations of phenol, cyclopentadiene and citronellol with photosensitizers ionically bound at a polymeric ion exchanger
TL;DR: In this paper, tetrasulfophthalocyanines and rose bengal were employed as photosensitizers in the photooxidation of phenol, cyclopentadiene and (S)-(−)-citronellol.
Journal ArticleDOI
Synthesis of polymeric and low molecular weight phthalocyanines from nitriles and metal carbonyls on SiO2 and TiO2 and catalytic activities in the sulfide oxidation

TL;DR: In this paper, a new method for coatings of polymeric phthalocyanines and for comparison also of low molecular weight polymeric PHTHCyanine metal complexes (W, Cr, Mo, Co) on quartz and titanium dioxide was developed by the reaction of metal carbonyls adsorbed on the carriers with tetracarbonitriles or phthalonitrile.
Journal ArticleDOI
Photooxidation of sulfide, thiol, phenols, and cyclopentadiene by artificial light and solar light irradiation
TL;DR: The photooxidations of the toxic products sulfide, 2-mercaptoethanol and phenols under partial mineralisation in aqueous alkaline solution and the photooxidation of cyclopentadiene in ethanol in order to produce fine chemicals is described in this paper.
