Reference excerpt

Junes Ipaktschi (born October 25, 1940, in Tabriz, Iran) is an Iranian organic chemist and professor of the Department of Organic Chemistry at the University of Giessen.

Life 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.

Research Ipaktschi is known for the use of ethereal solutions of lithium perchlorate as a medium for organic reactions and organometallic chemistry.

Worked examples

Example 1 — a first encounter with Junes Ipaktschi

Start with the simplest possible case. Write down what Junes Ipaktschi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Junes Ipaktschi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Junes Ipaktschi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Junes Ipaktschi

In research: Junes Ipaktschi appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Junes Ipaktschi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Junes Ipaktschi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 20th-century German chemists, 21st-century German chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Junes Ipaktschi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
