ESR data of the stannyl radical (i-PrsPh)&-at temperatures betxveen -140 and +200Β°C are presented. In solution, the isotropic l19Sn hyperfme coupling decreases with increasing temperature (20Β°C < T < 200Β°C) indicating that the radical is non-planar and configurationally stable. At -140Β°C in a toluen
## Abstract 2β(2β, 3β, and 4βPyridyl)benzoxazole derivatives were prepared in excellent yields by the oxidative cyclization of phenolic Schiff bases with thianthrene cation radical perchlorate in the presence of 2,6βdiβ__tert__βbutylβ4βmethylpyridine.
