The preparation of chiral, enantiomerically pure substances is a crucial endeavour of chemistry and one of high value to our society. Herein is presented a new approach to asymmetric synthesis, relying on the use of aromatic compounds as feedstocks for the production of enantiomerically pure products relying on clean processes and with minimal amounts of waste. more
The rapidly expanding field of gold catalysis and the growing number of research groups involved in this area clearly highlight its potential in synthetic organic chemistry. However, the continuous increase of the prize of gold as well as other noble metals during the last years makes the development of new strategies compulsory that allow for an efficient recovery and recycling of these expensive catalysts after their use. Here we show how ligands based on phosphenium and other phosphorus-centered cations can offer a potential solution to this problem. more
The fifth centenary of the birth of Giorgio Vasari (1511–1574), one of the precursors of modern art history, calls for a reconsideration of aspects of his oeuvre, from his – often underestimated and therefore little studied – role as one of the most successful and productive painters and architects of his generation, to his more famous literary work, The Lives of the Most Excellent Painters, Sculptors and Architects. This offers both new approaches for the history of science of our own discipline as well as intensified methodological reflection. more
