The compounds 10 - 15 generated in the reaction of p-hydroxyphenylcinnamic acid 7 with HNO2, were isolated and spectroscopically characterized. 10 is supposed in the literature to be a 1,2,3-oxadiazole 3-oxide 5; it actually has the constitution of a furoxan, and crystallizes in the space group P21/c = 2 ? (I)>.The compound with one oxygen less is the corresponding furazan 11.Alkaline degradation of the main products 10 and 12 leads to 13 and 25 - 27 and to 28, respectively.
