Kenkichi Sonogashira

Kenkichi Sonogashira is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kenkichi Sonogashira rather than just read about it. In short: Kenkichi Sonogashira (薗頭健吉, Sonogashira Kenkichi; born 25 October 1931) is a Japanese chemist and was a professor of chemistry at Osaka University in Japan. He discovered the Sonogashira coupling in 1975.

Key takeaways

Kenkichi Sonogashira belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kenkichi Sonogashira to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kenkichi Sonogashira from memory before moving on to harder problems.

Reference excerpt

Kenkichi Sonogashira (薗頭健吉, Sonogashira Kenkichi; born 25 October 1931) is a Japanese chemist and was a professor of chemistry at Osaka University in Japan. He discovered the Sonogashira coupling in 1975. Sonogashira was later a professor at Osaka City University and retired in 2004.

Worked examples

Example 1 — a first encounter with Kenkichi Sonogashira

Start with the simplest possible case. Write down what Kenkichi Sonogashira 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 Kenkichi Sonogashira 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 Kenkichi Sonogashira 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 Kenkichi Sonogashira

In research: Kenkichi Sonogashira 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 Kenkichi Sonogashira 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: Kenkichi Sonogashira is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, Academic staff of the University of Osaka, Chemist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Kenkichi Sonogashira 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.
