The synthesis, characteristics, properties and metal-ion interactions of 2-(3'-sulphobenzoyl)-pyridine thiosemicarbazone and phenyl thiosemicarbazone have been studied. These substances exhibit three pK values in aqueous solution, and form water-soluble chelates with high molar absorptivities, which may be used in analysis, especially the iron(II ...

AbstractThionaphthenchinon (I) reagiert mit Thiosemicarbazid (III) in alkoholischer Lösung in Gegenwart von etwas Wasser über die offenen Formen (II) und (IV) zu dem β‐Thiosemicarbazon (V), das sich durch Behandlung mit Natronlauge über die offene Form (IV) zu dem Triazinthion (VI) isomerisieren läßt.

The hydrolysis of coordinated thiosemicarbazones was studied. It was found that the nickel(II) ion promotes the reaction. Steric and electronic influences were found. The hydrolysis ofATSC in the trigonal bipyramid compounds [M(ATSC)2Cl]Cl [M=Fe(II), Co(II), Ni(II)], is higher with the Ni(II) complex, the compound with the shorterM-N distance.

Über einige heterozyklische Thiosemicarbazone
Experientia, 1952Description of 30 thiosemicarbazones of heterocyclic Aldehydes. Some of these compounds show tuberculostatic activityin vivo superior to p-Acetylaminobenzal-dehyde-thiosemicarbazone which statement was already made independently by French and American research groups.
