Cycloaddition reactions of sodium dinitroxytrioxide (Angeli's salt)
Torun, Lokman,Mohammad, Taj,Morrison, Harry
, p. 5279 - 5282 (1999)
Angeli's salt undergoes a quantitative reaction with 1,3- diphenylisobenzofuran in a methanol/water solution at room temperature to give a product (1) explicable by an initial [4+2] cycloaddition reaction. Under the same conditions, Angeli's salt reacts with 1-naphthaldehyde to give 1-naphthoic acid in good yield. This reaction can also be explained by an initial [2+2] cycloaddition to give a hydroxamic acid, which is then hydrolyzed to the carboxylic acid.
