SYNTHESIS OF DIARYLIC COMPOUNDS BY PALLADIUM CATALYZED REACTION OF AROMATIC TRIFLATES WITH BORONIC ACIDS

Huth, Andreas,Beetz, Ilse,Schumann, Ingrid

, p. 6679 - 6682 (1989)

The known triflates 3c-5c react with the boronic acid 2j to produce the known biarylic compounds 3j-5j.An extension of this new procedure by reacting the novel triflate 1c with the arylboronic acids 2f-j affords the new correspondingly arylated compounds 1f-j.
