According to the editors (both of the National Center for Scientific Research, France), the selective activations of terminal alkynes and propargylic alcohols via vinylidene- and allenylidene-metal intermediates play an important role in recent developments of synthetic methods with useful applications in the synthesis of natural products and molecular materials and have opened new catalytic routs toward anti-Markovnikov additions to terminal alkynes, carbocyclizations, or propargylations.
