The title compound, C(8)H(9)N(3)S, contains two mol-ecules in the asymmetric unit. One mol-ecule is close to being planar (r.m.s. deviation from the mean plane = 0.06 Å for the non-H atoms), while the other exhibits a dihedral angle of 21.7 (1)° between the benzene ring and the mean plane of the thio-semicarbazone unit. Inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into layers parall...

Ten newly synthesized organophosphorus derivatives containing substituted chalcones and substituted chalcone semicarbazones were tested for their antifungal efficacy against Colletotrichum falcatum, Fusarium oxysporum, Curvularia pallescens (all sugarcane pathogens). The O,O-diethylphosphate derivatives containing 2-chlorochalcone and 2-chlorochalcone semicarbazone exhibited 70-85% mycelial inh...

Preparation of bisbenzofuran-2-yl-methanone (1), the corresponding ketoxime 4, semicarbazone and thiosemicarbazone 3a and 3b, ether derivatives of the ketoximes 5a-j and the alcohol 2 are described. These substances have been prepared in excellent yields. All the synthesized compounds except 5i have been tested against five different microorganisms and some of them were found to be active again...

The asymmetric unit of the title compound, C(6)H(11)N(3)O, consists of two independent mol-ecules in which the cyclo-pentane rings adopt envelope conformations with CH(2) grouping as the flap and the semicarbazone groups are essentially planar, with maximums deviation of 0.0311 (12) and 0.0285 (12) Å. In the crystal, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules to form sheets lying...
