Transition metal-catalysed hydroacylation represents a powerful strategy for the direct formation of ketones by addition of the formyl C–H bond of an aldehyde across unsaturated substrates such as ...

Transition metal catalysis has revolutionised the synthesis of organosulfur compounds by enabling efficient formation and manipulation of carbon–sulfur (C–S) bonds under mild conditions and with broad ...

A transition-metal-free click polymerisation of aldehyde-activated internal diynes and diphenols has produced a new family of ...

Precious transition metals like platinum and palladium are used as catalysts to speed up chemical reactions that produce carbon-nitrogen bonds. UCLA organic chemists have figured out how to make ...

To know the electron configuration of atoms and ions of the d-block elements of Period 4 (Sc–Zn), given the atomic number and charge To understand the elements Ti–Cu as transition elements To ...

Speeding up chemical reactions is key to improving industrial processes or mitigating unwanted or harmful waste. Realizing these improvements requires that chemists design around documented reaction ...

Researchers developed a way to quickly calculate the transition state structure of a chemical reaction, using machine-learning models. During a chemical reaction, molecules gain energy until they ...

MIT chemists have developed a computational model that can rapidly predict the structure of the transition state of a reaction (left structure), if it is given the structure of a reactant (middle) and ...

During a chemical reaction, molecules gain energy until they reach what's known as the transition state—a point of no return from which the reaction must proceed. This state is so fleeting that it's ...
