Oxidation of 2-tert-butyl-3-(tert-butylamino)-2H-indazoles with lead(IV) oxide yields red, stable radicals, which can be distilled under high vacuum and recrystallized. They revert to their precursors on Pd-catalysed hydrogenation. Configuration and

(Arylimino)diaziridines rearrange in several cascade reactions at temperatures 60-100 °C. Those that possess unoccupied ortho positions yield fluorescent 3-amino-2H-indazoles and 2-amino-1H-benzimidazoles. If both ortho positions are blocked by meth

Iminodiaziridines are synthesized by (i) 1,3-dehydrochlorination with potassium tert-butoxide of N-chloroguanidines, generated in situ from N,N′,N″-substituted guanidines with tert-butyl hypochlorite, and (ii) base-mediated 1,3-elimination of sul

The objective of this investigation was to compare the influence of titania, zirconia and silica on synthesis and properties of epoxide group containing organically modified silicates. These materials were prepared from the epoxysilane ( MeO ) 3 SiC

Methods of synthesizing materials for hard contact lenses were developed by hydrolysis and condensation of an epoxide substituted alkoxysilane and Ti-alkoxides. To enforce sufficient tensile strength, polymethacrylates were incorporated as linear cro
