Benzoin thiosemicarbazone

Acta Crystallographica Section E Structure Reports Online, 2005
In the title compound, C15H15N3OS, the thio­semicarbazone moiety is planar, with a maximum deviation of 0.0369 (11) A, and has an E configuration. The planar phenyl rings make dihedral angles of 26.56 (9) and 81.20 (5)° with the plane of the thio­semicarbazone moiety. In the mol­ecule, there are two intramolecular interactions of types N—H⋯O and N—H⋯N.

A study on ester thiosemicarbazones [PDF]

, 1997
The cyclization of ester thiosemicarbazones to two different heterocycles was studied for some new thiosemicarbazones, and only the formation of 1,2,4-triazol-5-thiols was attributed to the regioselectivity of the ring closure reaction, due to a steric ...
