6 were obtained from thioamides and α-bromoketones by a four-step reaction.

Three kinds of thioamide-group chelating fiber were synthesized by cross-linking of initial polyacrylonitrile(PAN) fiber with anhydrous hydrazine, ethylenediamine, diethylenetriamine respectively and following chemical modification with sodium sulfide.

A new chelating fiber containing thioamide group is synthesized by cross-linking of polyacrylonitrile(PAN) fiber with ethylene-dimine and following with chemical modification with sodium sulfide using DMF as solvent.

In the present work, the CASSCF method was employed to optimize structures of thiocamphor in the lowest five electronic states (S0, T1, S1, T2, and S2), which was followed by single-point energy calcu- lations at the MR-CI level.
