摘要

The gold-catalyzed hydration of 2-phenyl-or 2, 2-diphenylcyclopropyl acetylene, sensitive probes to trace the formation of vinyl carbocations, provides exclusively the corresponding cyclopropyl methyl ketones. On the other hand, in the Ag (I)-or Fe (III)-catalyzed hydration, a profound vinyl carbocationic character appears in the initially formed metal–alkyne complexes, as judged by the partial (Ag+) or exclusive (Fe3+) formation of allene-type ...
