NMR spectroscopic studies show that Tryller's and Schmitz's compounds have furoxan (3) and 1,4,2,5‐dioxadiazine (11) structures, respectively. Combined NMR spectroscopy and X‐ray crystallography show that the products obtained by action of dinitrogen tetroxide and 5% sodium hydroxide on Tryller's compound have furazano[3,4‐d]pyridazine 1,5,6‐trioxide and furazano[3,4‐d]pyridazine 5,6‐dioxide structures 5 and 8, respectively. They also show that the product obtained by action of dinitrogen tetroxide on Schmitz's compound has a dinitroethyl‐1,4,2,5‐dioxadiazine structure 12.

Abstract
NMR spectroscopic studies show that Tryller's and Schmitz's compounds have furoxan (3) and 1,4,2,5‐dioxadiazine (11) structures, respectively. Combined NMR spectroscopy and X‐ray crystallography show that the products obtained by action of dinitrogen tetroxide and 5% sodium hydroxide on Tryller's compound have furazano[3,4‐d]pyridazine 1,5,6‐trioxide and furazano[3,4‐d]pyridazine 5,6‐dioxide structures 5 and 8, respectively. They also show that the product obtained by action of dinitrogen tetroxide on Schmitz's compound has a dinitroethyl‐1,4,2,5‐dioxadiazine structure 12.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
