A general method for preparation of ferrocene-containing monoamines (5-7) and diamines (10, 11) starting from the corresponding quaternary ammonium iodide 3 and ferrocene mono-(4) and dithiaaliphatic acids (8, 9) was developed. Amines obtained have been characterized as acet-and benzamides (12-15).
In a study of the specificity of Laciobacillvs helveticus nucleoside deoxyribosyltrqnsferasel, it was observed that 5-aminoimidazoIe carboxamide was a sub&a&, showing that apart from the imidazole ring a complete fused six-membered ring was not necessary. On the other hand, imidazole did not react,
A satisfactory system for thin-layer chromatography of tetrazolium salts and their formazan reduction products has been devised. The methods developed permit the detection of contaminating conzpouncls in commercial samples of tetrazolium salts. When working with formazans it is necessary to control
