Article abstract of DOI:10.1246/cl.1994.2055

A facile and efficient synthetic procedure of o-phenylenedizinc(II) compound from o-diiodobenzene and zinc powder under the irradiation of ultrasound is reported.The compound was proved to be a unique reagent supplying o-phenylenedianion of high chemoselectivity.Symetrically 1,2-diaryl or diaroyl substiituted benzenes were obtained in good yields by Pd(0)-catalyzed cross-coupling of the compound with aryl halides or acyl halides.
