Improved routes to the quinoxalinone acid chloride 1 and the 3-methyl-quinoxalinone 21 are described. These intermediates are used to obtain the fluoroionophores 15–19 and 27–29, respectively. The effects of the complexation of metal ions by the fluoroionophores is discussed. A red pigment 26 is obtained from 21.
