For the first time, researchers have imaged and identified the bond configuration of the intermediates in a complex sequence of chemical transformations of enediyne molecules on a silver surface and ...

Chemical reactions rarely go from start to finish in a single step, as intermediates form during the transition between starting materials and final products. For example, when our bodies synthesize ...

Understanding the microscopic mechanisms of surface-catalysed organic reactions at solid/liquid and solid/gas interfaces is a grand challenge for modern heterogeneous catalysis and its application to ...

An international group of researchers has been able to isolate and characterize an important chemical intermediate whose existence has, so far, only been inferred from indirect experimental evidence.

Immobilizing small synthetic molecules inside protein crystals proves to be a promising avenue for studying intermediate compounds formed during chemical reactions, report scientists from Tokyo Tech.

Researchers at the University of Hamburg, the University of Toulouse, and the DESY and ESRF research institutes have observed ...

Chemists at Merck & Co. were carrying out a published procedure for preparing 2-bromo-3-methylbutenal (Org. Lett. 2007, 9, 4607). The reaction and workup were successfully carried out twice on a 10-g ...

A new technique offers a sharp picture of an elusive and ephemeral stage of a chemical’s life. By precisely measuring the energy of a molecule at the instant it morphs from one form to another, ...

One of the long-standing goals being pursued by chemists has been to succeed in following and directly visualising how the structures of molecules change when they undergo complex chemical ...
