Injection of three different organotin compounds such as tripalmitin, fentin and fenbutatin produced a significant increase in the hemolymph sugar level of intact crabs at Oziotelphusa senex senex apparently by stimulating release of the hyperglycemic hormone (HGH).

In the title organotin compound, [Sn(C(6)H(5))(C(10)H(15)N(3)O(2)S)Cl(H(2)O)], the Sn atom is coordinated by the S, O, and imine N atoms of the dinegative tridentate ligand, a chloride ligand, the ipso-C atom of a phenyl ligand and by a water mol-ecule in a distorted octa-hedral coordination environment. Coordin-ated water mol-ecules link the organotin mol-ecules by forming O-H⋯O hydrogen bonds...

A one-pot tandem Pd-catalyzed hydrostannylation/Stille coupling protocol for the stereoselective generation of vinyltins and their subsequent union, employing only catalytic amounts of tin, is described. By recycling the organotin halide Stille byproduct back to organotin hydride, a hydrostannylation/cross-coupling sequence can be carried out with catalytic amounts of tin. Such a process is mos...

Organotin(IV) compounds have found their place among a class of non-platinum chemotherapeutic metallo-pharmaceuticals exhibiting good antitumor activity. The cytotoxicity induced by the different kinds organotins has been related to several mechanism. In this review we report our last decade research activity concerning synthesis and chemical characterization new organotin(IV) derivatives conta...

In the analysis of organotin compounds, derivatization is required in order to achieve more volatile compounds prior to the use of techniques based on GC separation. Derivatization can be considered as one of the main critical steps in organotin analysis, since low yields of derivatization and losses of analytes can easily occur at this stage, and lead to an underestimation of their content in ...

OF ORGANOGERMANIUM AND ORGANOTIN DERIVATIVES OF HYDROXAMIC ACIDS Valery S. Petrosyan*, Natalia S. Yashina, and Sergei V. Ponomarev Department of Chemistry, M. V. Lomonosov University, Moscow 119899, Russia Hydroxamic acids as the precursors oftheir organogermanium and organotin derivatives have been themselves intensively studied fi’om the viewpoint of their potential biological activities [1-3...

A Pd-based heterogeneous catalyst (Pd(II)-MCM-41) derived from post-synthesis modification of mesoporous silica, MCM-41, has been successfully employed in catalytic Stille and Sonogashira cross-coupling reactions. The catalyst affords good yields in all cross-coupling reactions. Notably, the catalyst is capable of activating less reactive chlorobenzene with moderate yield in both the coupling r...
