reaction occurring in premicellar aggregates and the second to reaction in micelles. At low substrate concentration (7 × 10−6 M), second-order rate constants in the micellar pseudophase are dependent on the surfactant headgroup size, which is related to charge dispersion in the transition state. Nonmicellizing tri-n-octylmethylammonium ions (TOAMs) increase the reaction of 1 with hydroxideion. The
The one-pot reaction of 2-chloroquinoxaline with phenoxide ion derivatives utilizing Ag+ as catalyst provided an efficient method for the preparation of five novel quinoxaline derivatives.

activities by interacting with proteins and nucleic acids. Then, synthesis of such compounds is critical for the development of drugs. Unsymmetric HetAr-X-HetAr′ compounds were efficiently synthesized by rhodium-catalyzed heteroaryl exchangereactions, which involved equilibrium control by judicious design of organic heteroaryl reagents. This method allows synthesis of unsymmetric HetAr–O–HetAr′, HetAr–S–HetAr′
A series of 2-substituted quinoxaline derivatives including five novel compounds have been successfully synthesized from 2-chloroquinoxaline using microwave methodology. The yields of the quinoxalines synthesized through this method, were an improvement over the thermal methods usually employed.
