A robust dearomative denitration method has been developed through a radical ipso-cyclization process, leading to the synthesis of valuable phosphonated or trifluoromethylated azaspiro[4.5]trienones with good functional group tolerance. This approach represents a convenient and powerful way to activate nitroarenes in a radical manner.
