Photochemical approach to the synthesis of naturally occurring thienylacetylenes
D'Auria, Maurizio,Tofani, Daniela
, p. 9315 - 9322 (1992)
Three naturally occurring thienylacetylenes are synthesized through a photochemical coupling of 5-iodo-2-thienyl derivatives and 5-trimethylsilyl-2-thienylacetylene.
Photochemical oxidation of trans-α,α′-dimethylstilbene in the presence of α-terthienyl
D'Auria, Maurizio
, p. 3151 - 3154 (1994)
trans-α,α′-dimethylstilbene gave a new photoproduct when irradiated in the presence of both oxygen and α-terthienyl. This new product is due to an electron transfer process.
Tandem photoarylation-photoisomerization of halothiazoles: Synthesis, photophysical and singlet oxygen activation properties of ethyl 2-arylthiazole-5-carboxylates
Amati, Mario,Belviso, Sandra,D'Auria, Maurizio,Lelj, Francesco,Racioppi, Rocco,Viggiani, Licia
experimental part, p. 3416 - 3427 (2010/08/20)
The photochemical reaction between ethyl 2-chlorothiazole5-carboxylate and benzene gave no product. In contrast, the reaction with ethyl 2-iodothiazole-5-carboxylate gave ethyl 3-phenylisothiazole-4-carboxylate. The same behaviour was observed if the reac
Photooxygenation of α,α'-dimethylstilbenes sensitised by photochromic compounds
Salemi-Delvaux, Christiane,Luccioni-Houze, Barbara,Baillet, Gilles,Giusti, Gerard,Guglielmetti, Robert
, p. 5127 - 5130 (2007/10/03)
A convincing evidence of the ability of the coloured open forms or photomerocyanines of photochromic compounds to act as sensitiser of singlet oxygen is provided by photosensitised oxidation of reference olefins, cis- and trans-α,α'-dimethylstilbenes, to a hydroperoxide.
SYNTHESIS AND PHOTOCHEMICAL PROPERTIES OF NITROTHIENYL DERIVATIVES
D'Auria, Maurizio,Mauriello, Giacomo
, p. 542 - 545 (2007/10/02)
Some 2-nitrothienyl derivatives characterized by the presence of an aryl or heteroaryl substituent in the C-5 position were synthesized by using a photochemical coupling procedure.All synthesized compounds were demonstrated to be singlet oxygen sensitizers in the trans-α,α'-dimethylstilbene photooxidation.
Synthesis and photochemical behaviour of 4-nitroimidazoles in the presence of oxygen
D'Auria, Maurizio,D'Onofrio, Franco,Suwinski, Jerzy,Swierczek, Krzysztor
, p. 3899 - 3906 (2007/10/02)
Synthesis and photochemical properties of 1-aryl-4-nitroimidazoles are described. These compounds are good sensitizers of superoxide ion. Only 1-phenyl-2-methyl-4-nitroimidazole is a photosensitizer of singlet oxygen.
SENSITIZED PHOTOOXIDATION REACTIONS OF CIS-α,α'-DIMETHYLSTILBENE. SENSITIZER, TEMPERATURE, AND SOLVENT EFFECTS ON PRODUCT DISTRIBUTION.
Futamura, Shigeru,Ohta, Hiroyuki,Kamiya, Yoshio
, p. 697 - 700 (2007/10/02)
Sensitized photooxidation of cis-α,α'-dimethylstilbene(1) depends on sensitizer, solvent, and temperature.At room temperature, Ru(bpy)32+- or TPP- sensitized photooxidation reaction of 1 affords a dioxetane hydroperoxide(2), while only an allylic hydroperoxide(3) is obtained when RB or MB is used as sensitizer.At low temperature, 2 comes to be formed independent of the sensitizer used.
