The title complexes, (C3H12N2)[WS4] and (C6H18N2)[WS4], contain tetrahedral [WS4](2-) dianions, which accept a complex series of hydrogen bonds from the organic dications. The strength and number of these hydrogen bonds ...

The regioselective syntheses of N sup(1) and N sup(2) substituted triazoles through a 1,6-addition reaction of 1,2,3-NH triazoles to p-quinone methide were achieved under mild reaction conditions. The present reactions ...

In the extended structure of the title molecular salt, C sub(6) H sub(9) N sub(2)+.C sub(7) H sub(7)O sub(3) S sup(?), the cations and anions are linked by N-H...O hydrogen bonds to generate [010] chains.

The title compound, C10H18O7S2, was synthesized by reacting diethylene glycol with allyl chlorosulfonate in the presence of pyridine. The asymmetric unit consists of half a molecule, which is located on a twofold rotation ...

The present review provides a comprehensive overview of the synthetic methods developed recently for 6H-Indolo[2,3-b]quinoline. The review is classified into the following: 1) inheriting indole skeleton and constructing ...

The ab initio calculation of the title compound was carried out at HF as well as DFT level of theory. The full geometry optimization of the ligand was carried out using 6-31G(d) basis set. The results obtained were correlated ...

An account of synthetic methods developed for indolocarbazole alkaloids arcyriaflavin A and staurosporinone is presented. Based on a common pathway or key intermediate involved, all these methods are broadly grouped into ...

Acylation of 2-naphthol (2), 1-naphthol(6) and resorcinol (11) with salicylic acid (1) in the presence of PPA affords salicylate esters (4,7,13 and 14), 1,2-benzoxanthone (5), 3,4-benzoxanthone(8), 3-hydroxyxanthone(12), ...

Synthesis and modification of cost-effective sorbents for removing heavy metals from water resources is an area of significance. It had been reported that materials with biological origins, such as agricultural and animal ...
