Phenols Add To Alkynes Via Cooperative Gold
A new reaction uses cooperative gold catalysts to achieve an organic synthetic goal infrequently explored: adding tertiary alcohols and phenols to alkynes. Steven P. Nolan of the University of St. Andrews, in Scotland, and colleagues had previously developed a dinuclear gold hydroxide catalyst, [Au(NHC)]2(μ-OH)][BF4], where NHC is an N-heterocyclic carbene. They reasoned that this compound could behave as two catalysts and applied it to the hydrophenoxylation . . .
