The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...

New research presents a versatile method for the synthesis of primary, secondary, and tertiary amines containing two stereogenic centers. In a paper just published at the website of ACS Catalysis ...

the Biocatalysis research group at the University of Amsterdam’s Van ‘t Hoff Institute for Molecular Synthesis presents a versatile method for the synthesis of primary, secondary, and tertiary ...

and then coupling the imine to a primary or secondary amine. This coupling displaces the imine’s nitrogen in the form of ammonia, and forges a new C–N bond to produce a secondary or tertiary ...

Amines are considered to be the derivatives of ammonia. Amines are often categorised as primary, secondary and tertiary on the basis of the number of hydrogen atoms replaced by alkyl. When one ...

A big goal in chemistry is to find a simple way to produce amines from ammonia and unsaturated ... a versatile method for the synthesis of primary, secondary, ...

White and coworkers had developed a work-around for this problem when using primary amines as reagents, but the approach did not work with secondary amines. In the new research, the group sought a ...

This has the potential, White explained, for chemists to take a lot of different secondary amines and couple them to a lot of different olefins, both of which you can either buy or easily make.

(iii) Methylamine is a primary amine, thus it gives Carbylamine test whereas Dimethylamine doesn’t give this test because it is a secondary amine. (iv) Aniline is a 1° aromatic amine thus gives ...
