Abstract
Herein we report the synthesis of bulky N-heterocyclic carbene gold(I) complexes via an “on-metal” eightfold Suzuki coupling of a suitable precursor complex. An initial screening revealed the optimal reaction conditions furnishing a series of extremely bulky gold(I) complexes in extraordinary yields. One of these complexes shows one of the highest buried volumes published so far. This synthetic potential of this complex to open up completely new reactivity patterns was demonstrated by inverting the reactivity of gold catalysts towards 1,5-diynes, enabling a diastereoselective synthesis of benzofulvenes.
