Unconventional fluorination: The development of the chemoselective gold-catalysed hydrofluorination of terminal alkynes using aqueous HF and an easily accessible N-heterocyclic carbene-gold pre-catalyst is reported. Following the observation and isolation of unprecedented organometallic intermediates and computational studies, a catalytic cycle is proposed, featuring an in situ generation of the chemoselective
