Junes Ipaktschi (born October 25, 1940, in Tabriz, Iran)[ citation needed ] is an Iranian organic chemist [1] and professor of the Department of Organic Chemistry at the University of Giessen.[ citation needed ]
Junes Ipaktschi grew up in Tehran / Iran. After graduation in June 1958 at the Razi School in Tehran, he studied chemistry from 1958 to 1966 at the Heidelberg University. His doctoral thesis dealt with the field of Organic Chemistry under the direction of Heinz Staab. He then conducted research as an assistant in the same working group and habilitated in 1972 for the Organic Chemistry with a thesis on the photochemistry of unsaturated ketones. From 1972 to 1974 he did research as a postdoctoral fellow and visiting professor in the laboratory of William G. Dauben at the University of California, Berkeley. In 1973 he accepted an appointment at the Department of Chemistry at the University of Marburg and became a professor. In 1975 he was at the chemical Institute of Arya Mehr University (now Sharif University) appointed to Tehran and joined as a professor in his native country, Iran. In 1978 he moved to the newly founded Reza Shah Kabir University (now Mazandaran University) and worked there as a professor for chemistry. He was for a time as director of the University and also head of the Chemical Institute operates. From 1980 until retirement, in 2005, he was professor of chemistry at the University of Giessen. 1992–1995 he was dean of the chemistry department of the University and 2001–2002 executive director of the Organic Chemical Institute there. In addition to several visits as a visiting professor at various universities in Iran, he was invited in 2001 as a visiting professor at the National Institute of Advanced Industrial Science and Technology, Tsukuba / Japan and spent three months there. In 1999, Ipaktschi was awarded the Kharazmi Award.
Ipaktschi is known for the use of ethereal solutions of lithium perchlorate as a medium for organic reactions and organometallic chemistry.
Robert Howard Crabtree is a British-American chemist. He is serving as Conkey P. Whitehead Professor Emeritus of Chemistry at Yale University in the United States.

Organogermanium chemistry is the science of chemical species containing one or more C–Ge bonds. Germanium shares group 14 in the periodic table with carbon, silicon, tin and lead. Historically, organogermanes are considered as nucleophiles and the reactivity of them is between that of organosilicon and organotin compounds. Some organogermanes have enhanced reactivity compared with their organosilicon and organoboron analogues in some cross-coupling reactions.
Franz Hein was a German chemist and professor. He specialized in the chemistry of organic chromium and other metal compounds. He was the son of the artist Franz Johann Erich Hein (1863–1927).

A metal carbido complex is a coordination complex that contains a carbon atom as a ligand. They are analogous to metal nitrido complexes. Carbido complexes are a molecular subclass of carbides, which are prevalent in organometallic and inorganic chemistry. Carbido complexes represent models for intermediates in Fischer–Tropsch synthesis, olefin metathesis, and related catalytic industrial processes. Ruthenium-based carbido complexes are by far the most synthesized and characterized to date. Although, complexes containing chromium, gold, iron, nickel, molybdenum, osmium, rhenium, and tungsten cores are also known. Mixed-metal carbides are also known.

Disulfidobis(tricarbonyliron), or Fe2(μ-S2)(CO)6, is an organometallic molecule used as a precursor in the synthesis of iron-sulfur compounds. Popularized as a synthetic building block by Dietmar Seyferth, Fe2(μ-S2)(CO)6 is commonly used to make mimics of the H-cluster in [FeFe]-hydrogenase. Much of the reactivity of Fe2(μ-S2)(CO)6 proceeds through its sulfur-centered dianion, [Fe2(μ-S)2(CO)2]2-.
