Chemistry of substituted quinolinones. V. Synthesis and use of quinolinylphosphazenes in amination of 8-methylquinoline

2,4-Dihalo-8-methylquinolines 2,3 have been prepared and subjected to azida tion and hydrazination reactions showing interesting regioselective propert ies to give compounds 4-10. The targeted aminoquiolines 13, 14, 15, 17, 19, 22 and 23 were obtained via hydrolysis of their corresponding phosphazenes 11, 12, 16, 18, 20 and 21, respectively. These phosphazenes have been prel iminary obtained by condensation of azido and/or tetrazoloquinolines 4, 5, 6, 10, 18 and 22, with triphenylphosphine in either boiling benzene or l,2- dichlorobenzene.
