Abstract

Chloride ligands are crucial in the gold-catalyzed cycloisomerization of allenynes to give hydrindienes such as 1, which are formally products of CH activation and formed completely selectively over the usual Alder-ene products (2; see scheme). This effect could be rationalized by a DFT study that ...
