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 11(a-h).
The thiosemicarbazone were obtained by the
thiosemicarbazide with 3-acetyl-2,5dimethylthiophene.
The reaction product (III) and
thiosemicarbazide were refluxed for 3 h in dilute hydrochloric acid.

thiosemicarbazide 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.
