title: Cobalt-Induced C-N and C-C Bond Formation via Metal-Stabilized alpha-CF(3) Carbenium Ion.
abstract: An alpha-CF(3)-carbenium ion stabilized by a bimetallic [Co-Co] cluster was prepared and isolated in good yield, starting from the corresponding alcohol by action of HBF(4)/Et(2)O. C-N and C-C bonds with nitrogen and carbon nucleophiles could be easily formed. Subsequent decomplexation gave the free substituted beta-CF(3) alkynes in good yields.
