The reaction of toluene solutions of indium trichloride and tris(trimethylsilyl)arsine resulted in the formation of a very fine dark-brown powder subsequently annealed up to 400°C to drive to completion the elimination of trimethyl-silyl-chloride. Nanocrystalline InAs was obtained. Similar reactions with InBr3 and Inl3 and P compounds have been discussed. Previously a similar reaction was described by Uchida et al. (1993) (reaction of indium acetylacetonate with tris(trimethylsilyl)arsine in refluxing triglyme). Subsequently the reaction with InCl3 was used by Guzelian et al. (1996) in the preparation of nano-crystal quantum dots. They compared different preparation methods and techniques useful to isolate specific size distributions. 

Using a sol-gel approach, a solution-based synthesis of nanocrystalline InNb04 has been reported for the first time. Indium acetylacetonate and niobium chloride, in the presence of benzyl alcohol, are used as precursors which react to yield the desired nanoparticles at 200 °C after 24 hr. These nanoparticles have been shown to have enhanced photocatalytic activity compared to the corresponding bulk materials, when the photodegradation of the dye Rhodamine B was tested under visible-light irradiation. 

SWV was used for the investigation of charge transfer kinetics of dissolved zinc(II) ions [215-218] and uranyl-acetylacetone [219], cadmium(II)-NTA [220] and mthenium(III)-EDTA complexes [221], and the mechanisms of electrode reactions of bismuth(III) [222], europium(III) [223,224] and indium(III) ions [225], 8-oxoguanine [226] and selenium(IV) ions [227,228]. It was also used for the speciation of zinc(II) [229,230], cadmium(II) and lead(II) ions in various matrices [231-235]. 

Indium mediates a highly enantioselective Barbier-type allylation of both aromatic and aliphatic aldehydes, using a chiral ethanolamine auxiliary, readily recoverable by acid extraction.193 Barbier coupling of aldehydes can be carried out in water using tin(II) chloride, with cobalt(II) acetylacetonate as catalyst.194...

Nanocrystals of BaTiO, are obtained by the thermal decomposition of MOeVD reagents (alkoxides such as BaTifOiCCjHis) [OCH(CH,),],) in diphenyl ether containing oleic acid, followed by the oxidation of the product with HjOi. Thermal decomposition of uranyl acetylacetonate in a mixture solution of oleic acid, oieylamine, and octadecene at 423 K gives uranium oxkle nanocrystals. Treatment of metal acetylacetonates under solvothermal conditions produces nanocrystals of metal oxides such as GajOj, ZnO and cubic lujOs. Nearly monodisperse InjOj nanocrystals have been obtained starting with indium acetate, oieylamine and oleic acid. TiOj nanocrystals can be prepared... 

When anhydrous indium chloride was dissolved in acetylacetone, the color of the solution was light yellow. The color of the solution changed to dark reddish-brown after it was refluxed at 60°C.
