Reaction of Nitroxides with Sulfur Containing Compounds II [1]. Preparation of Nitroxides Bearing an Isothiocyanate Substituent in View of the Nitroxyl Group Reduction with Thiophosgene
Autor: Jarosław Hupko, Jerzy Zakrzewski, Krzysztof Kryczka
Publikováno v: Monatshefte f�r Chemie / Chemical Monthly. 134:843-850
The reaction of thiophosgene with 2,2,6,6-tetramethylpiperidine-1-oxyl (used as a model nitroxyl radical) was examined. 2,2,6,6-Tetramethylpiperidine and 2,2,6,6-tetramethyl-1-hydroxypiperidine were identified as products. The reaction is not competi

4-Isocyano-2,2,6,6-tetramethylpiperidin- 1-oxyl: A Valuable Precursor for the Synthesis of New Nitroxides
Autor: Julia Jezierska, Jerzy Zakrzewski, Jarosław Hupko
Publikováno v: Organic Letters. 6:695-697
To enrich the limited set of isonitriles typically employed, 4-isocyano-2,2,6,6-teramethylpiperidin-1-oxyl (1) is proposed as an isonitrile bearing a nitroxyl moiety. Isocyanide 1 was used in some reactions characteristic of isonitriles. Isoselenocya
