Microwave spectra of 1,3,4-thiadiazole and [34S]1,3,4-thiadiazole. Dipole moment of 1,3,4-thiadiazole

Journal of Molecular Spectroscopy, 1962
Abstract The microwave spectra of 1, 3, 4-thiadiazole (I) and [ 34 S] 1, 3, 4-thiadiazole (II) have been recorded in the 15,000–30,000 Mc/sec region. Twelve and ten transitions, respectively, were assigned. The rotational constants of (I) are, A = 8907.51 ± 0.10, B = 5569.27 ± 0.02, and C = 3424.80 ± 0.03 Mc/sec. For (II), A = 8908.15 ± 0.20,

Synthesis of Several Mesoionic 1,3,4-Thiadiazoles

Journal of Pharmaceutical Sciences, 1965
Several mesoionic 1,3,4-thiadiazoles, more properly termed anhydro-4-phenyl-5-substituted-2-thio-1-thia-3,4-diazolinium thiols, have been synthesized. Physical constants for the compounds have been determined and recorded. Preliminary screening against selected microorganisms indicated some useful inhibitory activity in vitro .

1,3,4- Thiadiazoles—III

Tetrahedron, 1968
Abstract Some 2-aryl-5-chloro-1,3,4-thiadiazoles (I; X = Cl) were treated with several nucleophilic agents in different solvents. Displacement of chlorine by piperidine was chosen for a kinetic study in ethanol and in benzene, in the temperature range 30–60°.

Kristallin‐flüssige 1,3,4‐Thiadiazole. I. Biphenyl‐ und terphenylanaloge 1,3,4‐Thiadiazole

Journal für Praktische Chemie, 1980
Liquid Crystalline 1,3,4‐Thiadiazoles. I. Biphenyl‐ and Terphenyl Analogous 1,3,4‐ThiadiazolesThe synthesis of disubstituted 1,3,4‐ and 1,2,4‐thiadiazoles and 1,3,4‐oxadiazoles is described and their melting and clearing points are investigated. The influence of the heterocyclic ring system on the formation of crystalline liquid phases is discussed.

Microwave spectra of isotopic 1,3,4-thiadiazoles. Molecular structure of 1,3,4-thiadiazole

Journal of Molecular Spectroscopy, 1966
Abstract The microwave spectra of 2-D-, 2-13C-, and 3-15N-1,3,4-thiadiazole, C2H2N2S, were assigned and combined with earlier measurements to give a substitution structure of 1,3,4-thiadiazole. The molecule is planar with the following structural parameters: S,C=1.721A C,N=1.302A N,N=1.371A C,H=1.077A The result is ...
