Dichloro-3-[p-(l-ethoxycarbonylethyl)phenoxy]quinoxaline (127) gave 7-chloro-3- [p-( 1 -ethoxycarbonylethyl)phenoxy] -2( l//)-quinoxalinone (128),... 

Dichloroquinoxaline (65) and p-(l-methoxycarbonylethoxy)phenol gave 5-chloro-2- [p- 1 -methoxycarbonylethoxy)phenoxy)quinoxaline (66) (K2CO3,... 

An example of exchange with an oxygen-containing functional group is given which utilises a micellar system. Cationic micelles of cetyltrimethylammonium chloride and bromide, and tetradecyltrimethylammonium chloride and bromide, accelerate the reaction of 2-(4-nitro-phenoxy)quinoxaline with hydroxide ion to give quinoxalin-2(l/f)-one. ... 

Nucleophilic displacement of 2-chloro-3-phenylquinoxaline with methylamine at 100°-150° and with sodium phenoxide in excess of phenol of 100° gives the expected 2-methylamino- and 2-phenoxy-3-phenylquinoxalines.155 2-Chloroquinoxaline and its 3-phenyl derivative undergo ring closure with aminoacetaldehyde dimethylacetal to an imidazo[l,2-a]quinoxaline.136 Nucleophilic substitution of 2-chloro-quinoxaline with hydroxide ion in water is accelerated by cationic micelles and retarded by anionic micelles. These results were correlated with reactions of l-chloro-2,4-dinitrobenzene, and the characteristics of their transition states were discussed.137... 

Example Quizalofop—This compound is listed as phenoxy carboxylic acid, quinoxaline. Phenoxy carboxylic acid is the first chemical function in the listing, indicating that the synthesis route of quizalofop is found in the chapter under phenoxy carboxylic acids in the main text. 

Example Quizalofop—In the generic name index, this compound was found to be a phenoxy carboxylic acid and a quinoxaline. Quizalofop, therefore, appears twice in the chemical function index, once under the heading phenoxy carboxylic acids and once under quinoxalines. However, the listing under quinoxalines shows also (phenoxy carboxylic acid) which means that this is the chapter of the main text in which the synthesis of quizalofop is described.

Physical and mechanical characteristics have been measured and catalogued for the phenyl quinoxaline family in a related internal research project. From these data, 3,3 -Bis(4-[3-ethynyl phenoxy] phenyl)-2,2 -diphenyl-6,6 biquinoxaline (or BA-DAB-BA for short) was selected. Bis-(triphenyl phosphine) nickel II chloride was chosen as the initiator.
