A New Facile Synthesis of 4-Oxo-1,4-dihydrocinnolines

2-(2-Aminoaryl)-2-oxo-triphenylphosphoniumethylides 2a-d, readily available by standard procedures, are converted into 4-oxo-1,4-dihydrocinnolines 7a-d by treatment with nitrous acid and subsequent basic hydrolysis of the intermediate phosphoranes 6a-d.
