A new, regioselective synthesis of V-shaped 2,9-bis(6-(4-halophenyl)-1,2,4-triazin-3-yl)-1,10-phenanthrolines (4XPhBTPhen) ligands was developed, creating access to a simple and reliable synthesis of precursors for future supramolecular actinide complexing systems. Described is a reactant-directed regioselective synthetic method, which was found to be high yielding and reliable and yields exclusively 6,6′-phenyl BTPhen derivatives (including 4-chloro and 4-bromo) in five simple steps. Molecular and crystal structures of PhBTP and PhBTPhen products are fully determined and both were found to be in space group C2/c. Additionally, molecular and crystal structures of Z and E isomers of 2-hydrazono-2-phenylacetaldehyde oxime, a reagent in the synthetic route, reveal existence of strong intramolecular N-H?O hydrogen bonding in the Z isomer explaining its lower solubility in water.
A rapid synthesis of quinoxalines starting from ketones
Padmavathy,Nagendrappa, Gopalpur,Geetha
experimental part, p. 544 - 547 (2011/03/18)
A fast and general synthesis of quinoxalines, performed in two stages or as a one-pot reaction, starting from ketones via their α-hydroxylimino ketone derivatives, and condensation of the latter with 1,2-diaminobenzene under microwave irradiation, is described.
One-pot synthesis of 3-amino-4-aryl- and 3-amino-4-hetarylfurazans

, p. 1057 - 1059 (2007/10/03)
A "one pot" method for the synthesis of 3-amino-4-aryl- and 3-amino-4-hetarylfurazans from β-aryl- and 4-β-hetaryl-β-oxo acid esters was developed.
