hey there possible future self studying for chemistry look at this so you remember

the class: a meaningful discussion about molecule nomenclature

"Drop the final -e of the parent alkane name and add the suffix -amine."

An enhanced ruthenium-based catalyst for primary amine synthesis

Researchers at Tokyo Institute of Technology (Tokyo Tech) have developed a high-performance reusable ruthenium-based catalyst for the production of primary amines. Their method represents a major advance for the development of efficient catalysts that enable selective conversion of alcohols into primary amines under mild reaction conditions.

Primary amines are extremely versatile building blocks that are used in the preparation of many kinds of dyes, detergents, pharmaceuticals and agricultural chemicals. So far, several methods have been developed to produce primary amines using catalysts containing ruthenium, cobalt and platinum, all of which require the addition of molecular hydrogen. Synthesis of primary amines by direct substitution of alcohols with ammonia has been a longstanding challenge.

Now, researchers at Tokyo Tech report a heterogeneous ruthenium-based catalyst (Ru-MgO/TiO2) capable of driving direct amination of alcohols to produce primary amines without having to introduce hydrogen gas. They showed that the catalyst works at low temperatures, of around 100°C. The ready availability of alcohols and low cost of ammonia make the system both cost-effective and environmentally friendly.
