yielding dinitro products 7 and 8 (new stablefreeradicals) and 9 and 10 (corresponding hydrazines), whereas in the latter case (with the sodium aroxide 3) the aryloxy (syringyl) group substitutes one of the phenyl groups of DPPH in the para position, forming trinitro products 14 (new stablefreeradical) and 15 (corresponding hydrazine). Accompanying products were isolated by TLC and identified by their
