Autor: Andrés Barriga-González, Sebastián Simpson, Vicente Castro-Castillo, Cristian Suárez-Rozas

Publikováno v: Chemistry of Heterocyclic Compounds. 53:553-559

We followed a simple, inexpensive, and efficient route to synthesize a series of 3,4-dihydrobenzo[f]quinoxalin-6(2H)-one derivatives substituted in the ring B, with the expectation that this scaffold might exhibit antineoplastic activity. 5-Chloroben

Polyesters were synthesized by direct polycondensation of thiophene-2,5-dicarboxylic acid and five different silarylene-containing diphenols using a tosyl chloride/pyridine/N,N-dimethylformamide system as a condensing agent. Polymers were obtained in

Soluble pure silicon or germanium-containing poly(amide)s and their metallic composites (Cu or Au) were synthesized and characterized. Optical band gaps of pure polymer were comparable to an insulator behavior; however, the conductivity of some compo
