Dinitrobenzene Dinitrobiphenyl

VUmann reaction of 1,3-dinitrobenzene. 2,6-Dinitrobiphenyls can be prepared in good yield by the Cu(I) f-butoxide mediated reaction of aryl iodides and 1,3-dinitrobenzene. The reagent is conveniently generated in situ from CuCl and potassium t-butoxide in DME. [Pg.66]

A less general but related method for obtaining 2,6-dinitrobiphenyls consists of metallation of 2,6-dinitrobenzene using cof)per(I) r-butoxide in a mixture of pyridine and DME followed by coupling with an... [Pg.501]

Unfortunately, [Rh(C0)4] failed to give dicarbamates when dinitroarenes were used as substrates [30]. With 1,3-dinitrobenzene and 2,4-dinitrotoluene, only the corresponding diaminoarene and aminonitroarene were obtained. The dicarbamate was obtained in only 4 % yield from carbonylation of 4,4 -dinitrobiphenyl, whereas carbonylation of the corresponding 2,2 derivative gave a mixture of the internal azo (55 %) and urea (43 %) derivatives. Since no report of successful carbonylation of dinitroarenes has been reported for any of the... [Pg.100]
