Indium bromide chloride

Indium chalcogenide chlorides and bromides are obtained by heating mixtures of the chalcogenide and the halide in sealed ampoules to temperatures between 200 and 420°C (see Table XIX). For the preparation of the chalcogenide iodides. In and I2 are used instead of Inlj. InTel may be synthesized directly from the elements (161). 

In contrast to the non-trivial routes for the syntheses of pure aluminum(I) or gallium(I) subhalides, indium(I) chloride or bromide can simply be prepared by melting mixtures of elemental indium and indium trihalides [39]. When these in-dium(I) halides were treated with bulky alkyllithium compounds, deep violet orga-noelement indium dusters (13-18) were obtained [Eq. (3)] [40, 41].

Similar reactions occur with other halogens. Monohalides of indium include chloride, bromide and iodide. Monohalides are obtained by passing indium trihalides over heated indium ... 

In indium-mediated reactions, a catalytic use of expensive indium is desirable from an economical standpoint, and it has been achieved in combination with more electron-positive metals. Thus, allylation of aldehydes and ketones, as well as prenylation of 2-chlorobenzoquinone, has been performed by using metallic aluminum or zinc in combination with a catalytic amount of indium(m) chloride.63 Also, allylation of aldehydes and ketones with allyl bromide is carried out with a catalytic amount of indium powder (from 0.01 to 0.1 equiv.) in THF in the presence of manganese and chlorotrimethylsilane as the reducing and oxophilic agents, respectively (Scheme 2). 64,65... 

Dichloroindium hydride HlnCla, prepared from indium(m) chloride and DIBAL-H, works as a radical mediator. This compound reduces aryl iodides and bromides in the presence of Et3B as a radical initiator. Reduction of iodoacetals provides cyclized products in good yields (Equation (99)).385 Only a catalytic amount of InCl3 is necessary for complete consumption of the starting compound with stoichiometric DIBAL-H as a hydride source (Equation (100)). 

The introduction of a sugar moiety to the indole 3-position proceeds best with 2-substituted indoles indium(III) chloride is used in combination with a glycosyl bromide. ... 

Triethylsilane and trityl salts.or Trimethylsilyl Triftuoro-methanesulfonate are effective for the reduction of various ketones and acetals, as are combinations of Chlorotrimethylsi-lane and indium(III) chloride and Tin(II) Bromide and Acetyl Bromide. Isophthaldehyde undergoes reductive polycondensation to a polyether when treated with triethylsilane and Triphenyl-methyl Perchlorate. ... 

Mono-, di-, and trivalent bromides and iodides may be made by methods similar to the chlorides. The lower valence salts also disproportionate in water. Indium trifluoride [7783-52-0] InF., is sparingly soluble in water. It forms an ammonium double salt, SNH F TnF. [15273-84-4] which decomposes on heating to indium nitride [25617-98-5] InN. 

Apart from the fluoride, mercuric halides react explosively with potassium like all analogues of the other metals already mentioned. With mercurous salts, the reaction seems less violent since with mercurous chloride, molten potassium causes the mixture to incandesce without ever combusting. It is likely that other metals react too an extreme violent reaction was mentioned between indium and mercuric bromide.
