Patent ID: 6878850

Claim:
A process to prepare cross-coupling compounds of the formula R—Q comprising contacting a catalytic amount of a coordination compound having formula (I) with an aryl halide and an arylboronic acid or an arylamine; wherein M is a transition metal; X 1 is Cl or Br or I; X 2 is Cl or Br or I; X 3 is Cl or Br or I; and wherein R 1 and R 2 are independently selected from the group consisting of hydrocarbyl, substituted hydrocarbyl, heterocyclic, organometallic, H, Cl, Br, I, CN, SQ 1 , OQ 2 , PQ 3 Q 4 , NQ 5 Q 6 , SiQ 7 Q 8 Q 9 , and BQ 10 Q 11 where Q 1 , Q 2 , Q 3 , Q 4 , Q 5 , Q 6 , Q 7 , Q 8 , Q 9 , Q 10 , and Q 11 are independently selected from the group consisting of hydrogen, hydrocarbyl substituted hydrocarbyl, hydrocarbylamino, alkoxy, aryloxy, and heterocyclic, and optionally R 1 and R 2 can together form a ring; and wherein R is optionally an aryl ring; Q is independently selected from the group consisting of hydrocarbyl, substitute hydrocarbyl, heterocyclic, organometallic, H, CN, SQ1, OQ2, PQ3Q4, NQ5Q6, SiQ7Q8Q9, and BQ10Q11 where Q1, Q2 , Q3, Q4 , Q5 , Q6 , Q7, Q8, Q9, Q10, and Q11 are independently selected from the group consisting of hydrogen, hydrocarbyl substituted hydrocarbyl, hydrocarbylamino, alkoxy, aryloxy, and heterocyclic.
