Patent ID: 8920760

Claim:
A process for preparing a compound comprising Formula (III), the process comprising contacting a compound comprising Formula (I) with a compound comprising Formula (II) in the presence of an amine solvent comprising NR 1 R 2 R 3 to form the compound comprising Formula (III) according to the following reaction scheme: wherein: M is a metal selected from the group consisting of an alkali metal, an alkaline earth metal, and a transition metal; R 1 , R 2 , R 3 , R 4 , and R 5 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, and silyl, provided any two of R 1 , R 2 , and R 3 together may form a ring or a ring system selected from the group consisting of carbocyclic, heterocyclic, aryl, and heteroaryl, and R 4 and R 5 together may form a ring or a ring system selected from the group consisting of carbocyclic, heterocyclic, aryl, and heteroaryl; and x is an integer equal to the valence of M.
