    Notes: Abstract In contrast to Europe and North America, air pollution in Asia is increasing rapidly, resulting in both local air quality problems and higher acidic depositions. In 1989, an east-west group of scientists initiated a multi-institutional research project on Acid Rain and Emissions Reduction in Asia, funded for the past two years by the World Bank and the Asian Development Bank. Phase I, covering 23 countries of Asia, focussed on the development of PC-based software called the Regional Air Pollution INformation and Simulation Model (RAINS-ASIA). A 94-region Regional Energy Scenario Generator was developed to create alternative energy/emission scenarios through the year 2020. A long-range atmospheric transport model was developed to calculate dispersion and deposition of sulfur, based upon emissions from area and large point sources, on a one-degree grid of Asia. The resulting impacts of acidic deposition on a variety of vegetation types were analyzed using the critical loads approach to test different emissions management strategies, including both energy conservation measures and sulfur abatement technologies.

    Notes: Indium(III) and tin(IV) thiocarboxylates were prepared and characterized on the basis of their IR, 13C- and 19Sn-NMR data. Indium tris(thiobenzoate) (1) decomposes into a sulfido complex In (S)[S(O)CPh] (2a). The corresponding tris(thioacetate) In[S(O)CMe]3 is thermally too unstable to be isolated. The anionic tetrakis complex [Et3NH]{In[S(O)CPh]4} (3) was characterized by X-ray crystallography which revealed a distorted tetrahedral coordination at the In atom. X-ray diffraction analysis of the complexes BuSn[S(O)CPh]3 (4) and Cl2Sn[S(O)CPh]2 (7) showed distorted tetrahedral and cis-octahedral structures, respectively.

    Description / Table of Contents: Tetra-o-tolylzinn wurde in 45proz. Ausbeute mit Hilfe der Wurtz-Reaktion (Petroläther als Lösungsmittel; Hg als Katalysator) dargestellt. Durch Jodierung wurden daraus Tri-o-tolylzinnjodid und Di-o-tolylzinndijodid erhalten; ferner gelang die Darstellung von Tri-o-tolylzinnfluorid.
    Notes: Tetra-o-tolyltin has been prepared in 45% yield for the first time by Wurtz reaction. Optimum yield is obtained using pet-ether (b. p. 65-85) as solvent and small amounts of mercury as catalyst. A mechanism for the role of mercury in the reaction is suggested. Tri-o-tolyltin iodide and hitherto unknown di o-tolyltin di-iodide have been prepared in 65% and 55% yields respectively by controlled iodination of the compound. Tri o-tolyltin fluoride has also been synthesised for the first time in almost quantitative yield.
