Abstract:

The present invention relates to a process for the preparation of N-aryl amine and N-aryl amide compounds. Generally, the process of the present invention involves reacting a compound having a primary or secondary amino or amido group with an arylating compound, in the presence of a weak base and a transition metal catalyst, under reaction conditions effective to form an N-aryl amine or N-aryl amide compound, the transition metal catalyst comprising a Group 8 metal, e. g. , Ni, Pd, or Pt, and at least one carbene-containing ligand. Typically, the transition metal catalyst is formed in a preceding step from the conjugate acid form of the carbene ligand, a stoichiometric amount of a strong base, and a Group 8 metal atom or ion.

Abstract:

A vehicle workbench assembly for the exterior side of a truck bed is provided. The vehicle workbench assembly includes an integral workbench pivotably connected to the exterior side of the truck bed so as to move between a latched position nested in a sidewall cavity of the exterior side of the truck bed and an operable position perpendicularly extending therefrom. The integral workbench provides a wheel gap for accommodating the trucks wheel or wheel well in the latched position. A wheel gap plate is provided to fil the void of the wheel gap in the operable position.
