The Chemistry of Gallium

Emile-Clement Jungfleisch, 1839-1916. French chemist and pharmacist. Professor of organic chemistry at the Ecolc Superieure de Pharmacie and at the College de France. Although most of his ninety-nine papers were organic or pharmaceutical m nature, he also made valuable contributions to the chemistry of gallium and indium. 

Gallium has a stronger tendency to react with sulfur ligands than has aluminum. This is evident in the chemistry of gallium sulfides and related species, and in the fact that Ga forms... 

The chemistry of gallium is very similar to that of aluminum, its congener. Compounds of gallium almost always have a +3 oxidation state. While a few compounds with a +1 and +2 state have been postulated, these are controversial. 

The halides (especially the chloride) are the most commonly employed synthons in the chemistry of gallium. This is undoubtedly due to their ease of synthesis and high reactivity. While the trihalides have been traditionally the most extensively studied, the mono- and dihalides have come under recent scrutiny.
