| Abstract: | Diazotisation of the 5-amino function in 6,7-alkoxy-l-ethyl-l,4-dihydro-4-oxoquinoline-3-carboxylic acids led to various products. Dediazoniation was always accompanied by fission of the 6-alkoxy substituent; 6,7-methylenedioxy groups gave formaldehyde which could form a m-dioxino ring. Hydrolysis of the diazonium chlorides resulted in halo-dediazoniation. |
