Thanks to the superstrength of the silicon-fluorine bond, chemists at the University of Zurich have developed a new incarnation of the venerable Friedel-Crafts reaction: intramolecular aryl-aryl ...
From life-saving drugs and synthetic polymers to diverse advanced materials, the products containing organic compounds seem endless, thanks in part to regioselectivity, a feature in chemical reactions ...
THERE has been reported a critical minimum catalyst concentration of 0·03 per cent in the low-temperature polymerization of isobutene in the liquid phase using boron trifluoride, aluminium chloride or ...
The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

IN an earlier communication 1, evidence was given upon which the following conclusion was based. In the dimerization of di-isobutene and the polymerization of isobutene, it is essential that a trace ...
The development of metal-catalysed methods to functionalize inert C–H bonds has become a dominant research theme in the past decade as an approach to efficient synthesis. However, the incorporation of ...
DURING the past four years we have been investigating the mechanism of two closely allied reactions—the polymerization of isobutene and the dimerization of di-isobutene. Both these reactions are ...
