This invention relates to a novel solution phase process for the preparation of amide, carbamate, and sulfonamide combinatorial libraries. These libraries have utility for drug discovery and are used to form wellplate components of novel assay kits.
The invention relates to triazole salts, to their preparation and to applications thereof. The salts have at least one anionic triazolium group which carries at least one chlorosulphonyl, fluorosulphonyl or alkoxyfluorosulphonyl group, each of the anionic groups being combined with a proton or a cation that has a valency of less than or equal to 4. The salts are useful as synthesis reagents, as chemical-reaction or polymerization catalysts, and as ion-conducting materials for electrochemical generators, supercapacitors and electrochromic devices.

reacts with the fluoro-olefins CF2:CF2, CF2:CFCl, or CF2:CFBr at 100° to give nonacarbonyl-(trifluoromethylcarbon)tricobalt, CF3·CCo3(CO)9, in high yields. At lower temperatures, or with a shorter reaction time, tetrafluoroethylene gives mainly µ-tetrafluoroethylenebis(tetracarbonylcobalt), (OC)4Co·CF2·CF2·Co(CO)4, which rearranges quantitatively when heated in vacuo to form the novel compound, µ-t
