Heterocyclic compounds, aromatic benzoxazoles

A wide variety of different classes of fluorescent molecules has been investigated in the peroxyoxalate chemiluminescent systems. Among those screened were fluorescent dyes such as rhodamines and fluoresceins, heterocyclic compounds such as benzoxazoles and benzothiazoles, and a number of polycyclic aromatic hydrocarbons such as anthracenes, tetracenes, and perylenes. The polycyclic aromatic hydrocarbons and some of their amino derivatives appear to be the best acceptors as they combine high fluorescence efficiency with high excitation efficiency in the chemiluminescent reaction [28],... [Pg.112]

Methyl-substituted thiophenes are also capable of reaction with benzalaniline, provided that the 5-position carries a carbo- or heterocyclic aromatic group, as, for example, 2-(benzoxazol-2-yl)-5-methyl-thiophene (109), which yields the styryl derivative 110.11 The isomeric compound 111 may be obtained analogously from 2-(/ -tolyl)benzox-azole and Schiff s base from 2-formylthiophene and p-chloroaniline. [Pg.214]

Benzoxazole is a heterocyclic aromatic organic compound with a fused benzene-oxazole ring structure. Benzoxazole (l-oxa-3-azaindene) and several alkylated benzoxazoles have been identified in tobacco smoke. Benzoxazoles found in... [Pg.798]
