Hypervalent iodine(III)-induced oxidative [4+2] annulation of o-phenylenediamines and electron-deficient alkynes under metal-free conditions has been developed. The reaction allows for direct access to quinoxalines bearing two... more
A broad spectrum of highly substituted, biologically interesting title compounds is prepared in water and absence of any catalyst via bromination of β-dicarbonyl compounds, followed by condensation of the resulting bromides with... more
Two novel donor-acceptor (D-A)-type two-dimensional (2-D) polymers of PBDTSeQ (P1) and PBDTFQ (P2) were synthesized and characterized where 4,8-bis[5-(2-ethylhexyl) thiophen-2-yl] benzo[1,2-b:4,5-b'] dithiophene (BDT) was used as the... more
A simple, highly efficient and green procedure for the condensation of o-phenylenediamine with α-diketones in the presence of catalytic quantity of phthalic acid(0.0083 g, 5mol%) at room temperature was done. Using this method,... more
Monomeric and polymeric 5-nitroquinoxaline derivatives disubstituted in the 2 and 3 positions with 2-pyrrolyl (A), 2-furyl (B) and 2-thienyl (C) groups were prepared and characterized. The substituted 5-nitroquinoxalines were used as... more
