Mono- and diylide-substituted phosphines (YPhos): impact of the ligand properties on the catalytic activity in gold(<scp>i</scp>)-catalysed hydroaminations

Abstract

The monoylide-phosphines show a linear correlation between their donor strength and their activity in gold-catalysed hydroaminations, while steric congestions leads to lower activities of the diylide congeners despite their higher donor properties.
