Starting from tris(trimethylsilyl)silane the novel 2-chloro-3,4-bis-tris(trimethylsilyl)silyl-cyclo-diphospha-diazenium-tetrachloridogallate salt (7) was prepared in a six step synthetic procedure including the synthesis of N-tris(trimethylsilyl)silyl-aminodichlorophosphine (4) and 1,3-dichloro-2,4-bis-tris(trimethylsilyl)silyl-cyclo-diphospha-diazane (5). All intermediate products along the re...

This research evaluates the efficiency of nanosized ZnO in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of pH on heterogeneous catalytic ozonation. The combined use of ozone and ZnO catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. In addition, it was found that in ZnO catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...

Tris(2-chloro-benz-yl)tin hydroxide condenses with 3-mercapto-1,2,4-triazole to form the 1:1 cocrystal of the title compound, [Sn(C(7)H(6)Cl)(3)(C(2)H(2)N(3)S)]. The asymmetric unit contains two mol-ecules which differ only in the position of the nitro-gen-bound H atom of the triazole ring; one mol-ecule is linked to the other mol-ecule by an N-H⋯N hydrogen bond. In the second mol-ecule, two of...
