Indium complexes chlorides

Direct. Some radionucHdes are packaged in solution for direct sampling (qv) via a septum and injection into the patient. GalHum-67 is a marker of inflammation, infection, and various tumor types. Its half-life is 78.3 h and it is suppHed as the gallium citrate salt. Indium-111 chloride is suppHed for the labeling of white blood ceUs. The In chloride is mixed with oxine (9-hydroxyquinoline) to form a lipophilic, cationic In oxine complex, which enters the white blood ceU. The complex dissociates within the ceU, and the cationic In " ion is trapped within the ceU, owing to its charge. 

Indium phthalocyanine (PcInCl) can be prepared by treating indium(III) chloride with phthalonitrile in a high-boiling solvent like quinoline139 or 1-chloronaphthalene.143 Dimeric indium(III) phthalocyanine complexes of the type Pc2In,144 Pc3In2145 as well as a bicyclic phthalocyanine (Pc3/2ln)146 are also known. 

The rather complicated indium-phosphorus cluster framework 24 was obtained by the reaction of indium(III) chloride with PhP(SiMe3)2 in the presence of triethyl-phosphane [Eq. (12)] [29]. Apparently, a complex redox process occurred, in the course of which phosphorus atoms were oxidized by the formation of three P-P bonds, while six indium atoms were reduced from +3 to +2 accompanied by the formation of three In-In bonds. The In-In (average 274 pm) and P-P bond lengths (average 222 pm) represent localized single bonds. Other strategies for the... 

Reaction of indium(III) chloride with three equivalents of LiN(PPh2)2 in tetrahydrofuran affords the phosphazenide complex In[(PPh2)2N]3 (31) as a yellow solid. The solid-state structure shows that the six-coordinate indium atom is surrounded by three chelate rings in a propeller-like conformation.

In the past decade much effort in organoindium chemistry has been devoted to study of carbonyl allylation and aUylindation of carbon-carbon multiple bonds with allylic indium reagents. Apart from the conventional transmetalation of allyl-lifhium or aUyl Grignard reagents with indium(III) halides, a method widely used for preparation of allyhndium(III) compounds is the oxidative addition of metallic indium or indium(I) iodide to aUyhc substrates [3, 6]. Transmetalation of allylstan-nane with indium(III) chloride also gives allylindium(III) [7]. Allylindium(I) was recently prepared by transmetalation of allylmercury with metallic indium in water this compound is regarded as an intermediate in the allylation of carbonyl compounds in aqueous media [8]. A new method of preparation of allylic in-dium(III) reagents - reductive transmetalation of a 7r-allylpalladium(ll) complex with indium(I) salts has been reported this enables the use of a wide variety of allylic compounds and solvents [9]. 

The five-co-ordinate indium complexes CaFsInChLCL = MesN CHa-CHa NMes, 2,2 -bipyridyl, 1,10-phenanthroline, 2,2 6, 2"-terpyridyl, or PhaP-CHa CHa -PPha) are obtained by reaction of the dioxan complex CeFsInCIaCCaHsOa) (Vol. 2, p. 430) with the appropriate ligands. Reaction of the dioxan complex with pyridine, triphenylphosphine, or dimethyl sulphoxide yields indium(iii) chloride and a tris-pentafiuorophenylindium complex, and the compounds (CeFs)iiIn(quinolin-8-olate)3- ( = 1 or 2) have also been prepared. ...

New catalysts have heen recently developed for promoting the aldol-type addition of acetate-derived silyl ketene acetals with high efficiency 10-methylacridinium perchlorate (5 mol %), cationic mono- and dinuclear iron complexes (5 mol %), t-hutyldimethylsilyl chloride-indium(III) chloride (10 mol %), [l,2-henzenediolato(2—)-0,0 ]oxotitanium(20 mol%), phos-phonium salts (7 mol%), and trityl salts (5-20 mol%). ... 

An important area of application for indium(III) triflate is as a co-catalyst in other organometallic catalytic C-C bond forming reactions. The ruthenium-catalyzed three-component addition to form 1,5-diketones, reported by Trost, is a classic example (eq 21). The best catalyst employs a two-metal system composed of CpRu(COD)Cl and indium(III) triflate. The exact contribution of indium complex is unresolved although a part of it may be as a chloride scavenger.
