Solid-state photoreaction in two-component molecular crystals of thienylacetic acids and aza aromatic compounds
A series of two-component molecular crystals of 2-thienylacetic acid (1) or bis(2-thienyl)acetic acid (2) with aza aromatic compounds such as acridine (a) and phenanthridine (b) were prepared by crystallization from the solutions of both components. Irradiation of the crystals caused photodecarboxylation and radical intermediates which give decarboxylated and condensation products. The relationship between the crystal structures and the reaction paths are discussed. (C) 2000 Elsevier Science Ltd.

Melamine trisulfonic acid: A new efficient catalyst for the synthesis of aryldithienylmethanes
An efficient method has been developed for the synthesis of dithienylmethanes via bisarylation of aldehydes with thiophene in the presence of melamine trisulfonic acid as a catalyst under solvent-free conditions.

Conjugated Macrocycles Related to the Porphyrins. Part 3. Acid Catalyzed Condensations of Thiophenecarboxaldehydes with a Dipyrrylmethane
McDonald condensation of a dipyrrylmethanedicarboxylic acid 3b with 2,2'-dithienylmethane-5,5'-dicarboxaldehyde (2b) failed to give the expected dithiophene porphyrin analog 1b.However, oxidation of the reaction mixtures with DDQ gave trace amounts of porphyrin-like materials.Model studies indicate that these fractions are meso-dithienylporphyrins.The synthesis of three related α,γ-disubstituted porphyrins is described.

Photochemical reactions of Thienyl-, Bithienyl-, Terthienyl- and Thienylaroyl-methanols
Photochemical reactions of some thienyl-, bithienyl-, terthienyl- and thienylaroyl-methanols were studied in the neat state as well as in solvents like methanol and benzene.The terthienylmethanols were found to be susceptible to photo-sensitized oxidation which was inhibited by singlet oxygen quenchers.The photoproducts were isolated, characterised by spectroscopic methods and in some cases by synthesis.

SYNTHESIS OF 16-(4-IODOPHENYL)HEXADECANOIC ACID
16-(4-Iodophenyl)hexadecanoic acid was prepared in six steps by two methods: from 6-(2-thienyl)hexanoic acid and 6-phenylhexanoyl chloride or by alkylation, or acylation, of 2-thienylthiophene.Mass and 1H NMR spectra of some prepared compounds are discussed.The synthesis is suitable for preparation of radioactively labelled acids used as myocardial imaging agents.
