Identification of (phosphine)gold(i) hydrates and their equilibria in wet solutions

Abstract

The elusive gold(I) hydrates [Ph3PAu(OH2)]+TfO− and [((Ph3PAu)2OH)2]2+(TfO−)2 resulting from the most common gold(I) pre-catalyst Ph3PAuOTf have been characterized, leading to disclosure of the equilibria between gold oxo species in wet solutions.
