Gold Carbene or Carbenoid: Is There a Difference?
By reviewing the recent progress on the elucidation of the structure of gold carbenes and the definitions of metal carbenes and carbenoids, we recommend to use the term gold carbene to describe gold carbene-like intermediates, regardless of whether the carbene or carbocation extreme resonance dominates. Gold carbenes, because of the weak metal-to-carbene π-back-donation and their strongly elect...
متن کاملStable or not, woman or man: is there a difference?
In 2010 a dedicated group of researchers interested in women’s hearts, gathered in Brussels for a workshop discussing gender differences in cardiovascular disease (CVD). The workshop was undertaken as a result of an earlier report the same year from the European Heart Health Strategy (Euro-Heart) project showing that women are still under-represented in many cardiovascular clinical trials. Fewe...
متن کاملStructure of a reactive gold carbenoid.
A formal gold-for-chromium transmetalation allowed the gold carbenoid species [Cy3 PAuCAr2 ]NTf2 (11) (Ar=pMeOC6 H4 -) to be obtained in crystalline form. The structure in the solid state suggests that there is only little back donation of electron density from gold to the carbene center of 11 and hence very modest AuC double-bond character; rather, it is the organic ligand framework that is r...
متن کاملClickers or Flashcards: Is There Really a Difference?
A growing number of physics teachers are currently turning to instructional technologies such as wireless handheld response systems —colloquially called clickers. Two possible rationales may explain the growing interest in these devices. The first is the presumption that clickers are more effective instructional instruments. The second rationale is somewhat reminiscent of Martin Davis’ declarat...
متن کاملSystems and Processes – Is There a Difference ?
Abstract At a time when we are more conscious than ever before of the interconnectedness of our actions we are still publishing international standards that ignore the advances made in system theory and process management since the 1950s. David Hoyle author of the ISO 9000 Quality Systems Handbook, shows that we are rooted in the past using standards that promote unhelpful models of systems and...
