Abstract
The ever-increasing role of homogeneous gold catalysis in organic synthesis and the consequent
need to be able to rationally control the rate and outcome of such reactions has emphasised
the importance of each successive metal–carbon coordination step. Concentrating on alkyne
and allene cyclisation and upon reaction mechanisms postulated on the basis of empirical and
theoretical results, we have examined the coordination of gold fragments to triple bonds, the
modification of gold(I) precatalysts to effect specific reaction pathways or enantioselectivity
and the isolation of coordinated intermediates or model compounds thereof. Some of the
recent advances that have been made in various laboratories are described in this compact
review.
