This electronic density can be attributed to autocondensation of thiosemicarbazide
, generating [H.sub.2]S as a subproduct.
Representative Procedure for the Synthesis of 1-(4Fluorophenyl)-1,3-dihydroisobenzofuran-5-acyl Thiosemicarbazides
The thiosemicarbazone were obtained by the thiosemicarbazide
The reaction product (III) and thiosemicarbazide
were refluxed for 3 h in dilute hydrochloric acid.

and thiosemicarbazones," Coordination Chemistry Reviews, vol.
Synthesis of two series, 20,21(a-c), of Mannich bases of 1,5-benzodiazepines was carried out and evaluated for the anticonvulsant activity by isoniazid and thiosemicarbazide
induced convulsion model (Figures 20 and 21).
Ethanol solution (15 ml) of VBOPE (1 mmol) was added dropwise to a solution of thiosemicarbazide
hydrochloride (1.1 mmol) and pyridine (1.1 mmol) in ethanol at room temperature, and the mixture was refluxed for 12 h at 70[degrees]C and then cooled and poured slowly into excess water (32).
Benzoic acid (0.1 mol) and thiosemicarbazide
(0.1 mol) in phosphorous oxychloride (30 mL) were refluxed gently for 30 min and cooled followed by careful addition of water (90 mL).
Firstly, Hthiomen was prepared from thiosemicarbazide
and ([+ or -]) menthone (1: 1 molar ratio).
A mixture of thiosemicarbazide
(1.0 M), Carbon disulphide (1.2 M) and dimethyl formamide (40 mL) was refluxed for 3 h.
