Consecutive cross-coupling of o-phenylenedizinc compound with acyl and/or aryl halides in the presence of Pd(0)-tris(2,4,6-trimethoxyphenyl)phosphine

Consecutive cross-coupling of an o-phenylenedizinc compound 1 with two different acyl or aryl halides or acyl and aryl halides was accomplished in one pot by the catalysis of Pd(0)-tris(2,4,6-trimethoxyphenyl)phosphine to yield a variety of functionalized unsymmetrical 1,2-disubstituted benzenes in good yields.
