A Pd(OAc).sub.2 /diazabutadiene system has been developed for the catalytic cross-coupling of aryl halides with arylboronic acids. A combination of the diazabutadiene DAB-Cy (1, N,N'-Dicyclohexyl-1,4-dizabutadiene) and Pd(OAc).sub.2 was found to form an excellent catalyst for the Suzuki-Miyaura cross-coupling of various aryl bromides and activated aryl chlorides with arylboronic acids.

Un sistema di Pd(OAc).sub.2 /diazabutadiene è stato sviluppato per collegarsi catalitico degli alogenuri arilici con gli acidi arylboronic. Una combinazione della Limanda-Cy del diazabutadiene (1, N, N'-Dicyclohexyl-1, 4-dizabutadiene) e di Pd(OAc).sub.2 è stata trovata per formare un catalizzatore eccellente per collegarsi di Suzuki-Miyaura di vari bromuri arilici ed ha attivato i cloruri arilici con gli acidi arylboronic.
