More particularly, the present invention relates to the preparation of 2- substituted azaindoles from an ortho-gem-dihalovinylaminopyridine or from an ortho- gem-dihalovinylaminopyridine N-oxide compound and an organoboron reagent using a palladium metal pre-catalyst, base and a ligand. The present invention also relates to the preparation of 2-substituted thienopyrroles from an ortho-gem-dihalovinylthiophene compound and an organoboron reagent using a palladium metal pre-catalyst, base and a ligand. The present invention also relates to processes for the production of ortho-gem- dihalovinylaminopyridines which are useful as starting materials in the production of 2- substituted azaindoles, and novel compounds prepared by the processes. The present invention also relates to processes for the production of ortho-gem-dihalovinylthiophenes which are useful as starting materials in the production of 2-substituted thienopyrroles, and novel compounds prepared by the processes. Formulae (V) and (VII).
