Abstract
The facile preparation of a C4-symmteric tetratriazolium salt and its subsequent metalation to generate a series of tetranuclear mesoionic carbene gold(I) complexes is presented. The complete structural characterization of the metallic carbenes and the benefits of cooperative catalysis in the processes of hydroamination and hydrohydrazination of terminal alkynes are discussed.
