Indium organometallic compounds

Organometallic Compounds. The predominant oxidation states of indium in organometalUcs are +1 and +3. Iridium forms mononuclear and polynuclear carbonyl complexes including [IrCl(P(C3H3)3)2(CO)2] [14871-41-1], [Ir2014(00)2] [12703-90-1], [Ir4(CO)22] [18827-81 -1], and the conducting, polymeric [IrCl(CO)3] [32594-40-4]. Isonitnle and carbene complexes are also known.

Organometallic compounds can be incorporated into spun-on resist films either at the time of formation with even distribution or in a separate step after the resist has been applied to the substrate. For example, focused indium (146) or gallium (147) ion beams have been used to write a pattern directly on the resist surface. Subsequent plasma treatment then produced... 

Indium-mediated allylation of trialkyl(difluoroacetyl)silane 70 in aqueous media gives homoallylic alcohol 71 exclusively (Scheme 60). Both water and THF are essential for the allylation reaction. It is worth noting that homoallylic alcohol 71 is formed exclusively under these reaction conditions. On the contrary, enol silyl ether 72 is a major product of the fluorinated acylsilanes reaction with other organometallic compounds than indium via a Brook rearrangement and defluorination. Indium-mediated allylsilylation of carbonyl compounds provides a facile route to 2-(hydroxyethyl)allylsilanes. The allene homologs are similarly prepared (Scheme 61).244,244a... 

The coordination of pnictogen ligands to gallium alkyl compounds has also been used in purification techniques similar to those implemented for its indium analogs see Indium Organometallic Chemistry). For example, [RyGa L] where... 

Other organometallic compounds, including aUylic stannanes, allylic samarium, allylic germanium, and allylic indium compounds add to aldi-mines in the same manner. Aryltrialkylstannanes also add the aryl group to Al-tosyl imines using a rhodium catalyst and sonication. Catalytic enantioselective addition reactions are well known, including reactions in an ionic liquid.Allylic... 

Methyl, ethyl, propyl, and butyl halides are reduced at lead and tin cathodes to produce, respectively, the corresponding tetraalkyllead and tetraalkyltin compounds in excellent yield. Bismuth, gallium, indium, and thallium can be employed to prepare a variety of organometallic compounds. Feoktistov [2] and Hawley [4] have summarized many of these electrosyntheses.

A one-pot preparation of 4-iodomethyloxetan-2-one is reported (93SL899). Electrochemically generated organometallic compounds react with ketones in a Reformatsky reaction to give esters or lactones (93AG1218) and the formation of P-lactones is favoured when a sacrificial indium anode is used (94JOC3161).
