From 2,3-, 2,6-, 3,4- and 4,6-Dichloroquinolines to Isomeric Chloroquinolinesulfonyl Chlorides
摘要:
The action of sodium methanethiolate (in boiling DMF) on x,y-dichloroquinolines (1) (x=3 or 6, y=2 or 4) occured via chlorine ipso-substitution followed by methanethiolato-S-demthylation to yield x,y-quinolinedithiolates 2A which were: i) subjected to S-methylation, ii) oxidatively chlorinated to y,y'-bis(x-chloro-x-quinolinesulfonyl chlorides (5). Oxidative chlorination of y,y'-bis(x-chloro quinolinyl) disulfides (7) led to x-chloro-y-quinolinesulfonyl chlorides (8) accompanied by x,y-dichloroquinolines (1). Both quinolinessulfonyl chlorides 5 and 8 were efficiently converted to the corresponding quinolinesulfonamides 6 and 9.

An organic EL element includes an organometallic complex including a rhenium atom; one ligand which has a coordinated nitrogen atom and a coordinated oxygen atom, each coordinated with the rhenium atom, and has at least one π conjugation part; and the other ligand coordinated with the rhenium atom in such a way that the ligand saturates the coordination number of the rhenium atom and the charge of the whole organometallic complex is neutral.
