• Effects of Long Term Exposure: The substance may have effects on the kidneys. This may result in kidney impairment.
• Description: Indium lies in Group 13 (13th vertical column of the periodic table). it shows a wide variety of properties. It is considered to be metal of the 'poor metals' group. Indium (symbol Ga; CAS# 7440-74-6) is widely used in the electronics industry, its radioisotopes are used for diagnostic imaging in medicine. Though this element is not essential for human nutrition, it is widely distributed in low concentrations in the environment (Smith et al., 1978). Radioisotopes of indium have been used to label phagocytes and lymphocytes to localize inflammatory lesions (Dudley and Marrer, 1952; Abrams and Murrer, 1993). Despite early optimism, neither element has found wide use as a treatment for malignancies.
• Physical properties: Indium is silvery-white and malleable and looks much like aluminum and tin. However,it is softer than lead. Indium metal is so soft that it cannot be “wiped” onto other surfaces aswith a graphite pencil. Because it is noncorrosive and does not oxidize at room temperatures,it can be polished and will hold its shine better than silver. Its melting point is 156.60°C, itsboiling point is 2,075°C, and its density is 7.31 g/cm3.
• Uses: In bearing alloys; as a thin film on moving surfaces made from other metals. In dental alloys. In semiconductor research. In nuclear reactor control rods (in the form of an Ag-In-Cd alloy). Indium element is used in the synthesis of therapeutic particles containing metal ions; characterized by the use of unique ligand sets capable of making the metal ion complex soluble in biolgical medi a to induce selective toxicity in diseased cells. Indium’s low melting point is the major factor in determining its commercial importance.This factor makes it ideal for soldering the lead wires to semiconductors and transistors in theelectronics industry. The compounds of indium arsenide, indium antimonide, and indiumphosphide are used to construct semiconductors that have specialized functions in the electronicsindustry.Another main use is as an alloy with other metals when it will lower the melting point ofthe metals with which it is alloyed. Alloys of indium and silver and indium and lead have theability to carry electricity better than pure silver and lead.Indium is used as a coating for steel bearings to increase their resistance to wear. It alsohas the ability to “wet” glass, which makes it an excellent mirror surface that lasts longer than mercury mirrors. Sheets of indium foil are inserted into nuclear reactors to help control thenuclear fission reaction by absorbing some of the neutrons.

Development of a highly α-regioselective metal-mediated allylation reaction in aqueous media: New mechanistic proposal for the origin of α-homoallylic alcohols

10.1021/ja029276s

The research aimed to develop a highly regioselective metal-mediated allylation reaction in aqueous media for the synthesis of R-adduct homoallylic alcohols, which are important building blocks in the organic synthesis of biologically active molecules. The study proposed a new mechanism for the formation of these synthetically challenging molecules, suggesting that the reaction occurs in two stages: the initial formation of a γ-adduct followed by a rearrangement to form the thermodynamically more stable R-adduct. The research utilized indium, zinc, and tin as catalysts and involved a variety of aldehydes and allylic halides. The study concluded that the use of these metals in water, with specific conditions regarding the amount of water and temperature, could yield R-homoallylic alcohols with high selectivity and moderate to good yields, providing a new mechanistic understanding of metal-mediated allylation reactions and their high R-selectivity.
