Dynamical symmetry in a minimal dimeric complex

A macrocyclic dimeric diterpene with a C2 symmetry axis.

An unprecedented macrocyclic dimeric diterpene containing a C2 symmetry axis was isolated from Acacia schaffneri . This compound, named schaffnerine, was characterized as (5S,7S,8R,9R,10S,17S,5'S,7'S,8'R,9'R,10'S,17'S)-7,8:7,17':16,17:17,7':7',8':16',17'-hexaepoxy-7,8-seco-7',8'-seco-dicassa-13,13'-diene (1) from its spectroscopic data. Comparison of its experimental vibrational circular dichro...

Application of dimeric ortho-palladated complex of 2-methoxyphenethylamine in the Heck coupling reaction

The application of the [Pd{C6H3(CH2CH2NH2)-4-OMe-5-κ2-C,N}(μ-Br)]2 complex of 2-methoxyphenethylamine in the Heck coupling reaction was considered under both conventional and microwave irradiation conditions, and their results were compared. This complex is an efficient, stable and non-sensit...

Dynamical Electroweak Symmetry Breaking

These lectures explored the idea that the physics of electroweak symmetry breaking arises from novel strong dynamics. We started from the familiar strong-interaction dynamics of QCD, introduced simple dynamical electroweak symmetry breaking models whose strong dynamics imitate those of QCD, analyzed the limitations of these models, and finally moved on to theories whose dynamics differ from tho...

Dynamical Electroweak Symmetry Breaking

We review the status of and recent developments in dynamical electroweak symmetry breaking, concentrating on the ideas of technicolour and top quark condensates. The emphasis is on the essential physical ideas and experimental implications rather than on detailed mathematical formalism. After a general overview of the subject, we give a first introduction to technicolour, and extended technicol...
