Astatine-211At)ICoordination chemistry SummaiyThe natuie and ptopeities of inorganic "' At-species formed in aqueous solutions under alkaline, neutral, acidic and oxidative conditions are studied through extraction of At with a variety of organic solvents, followed by the determination of the cjuomatographic, re-extraction and interaction behaviour of the extracted activity. It is concluded from the R{ values (on SiO,) and the different affinities for a large amount of additives, that the extracted activity -formerly denoted as At-zero -exists of AtX Compounds that may form AtXL^ complexes, depending on the kind of solvent (L) used.

“…In order to study the photochemical behaviour of polyhalogenothienyl derivatives, we decided to synthesise 2,3-diiodo-5nitrothiophene (4) on the basis of a previous work starting from 2,3,5-triiodothiophene (3) via a nitration with nitric acid and acetic anhydride (Scheme 2). 28 In our hands this reaction not only gave 4 but also a mixture of 4 and 5 in 2 : 3 ratio (Scheme 2).…”

A new synthetic method for dithieno[3,2-b:2′,3′-d]thiophenes was developed. The approach involves three steps starting from thiophene: tetraiodation of thiophene, selective dialkynylations on the 2,5-positions of the tetraiodothiophene, and finally CuI/TMEDA catalyzed double annulations of 2,5-dialkynyl-3,4-diiodothiophenes by Na 2 S, to afford dithieno[3,2-b:2′,3′-d]thiophene and its derivatives.
