Application of the XCORFE Long Range Heteronuclear Correlation Sequence to Several Biphenyls and m-Quaterphenyls

A series of highly substituted biphenyls have been synthesized and carbon and proton NMR spectra have been assigned by a combination of 1D and 2D techniques.The XCORFE variation of the long range heteronuclear correlation experiment was found to be partic

Synthesis of Substituted Dibenzophospholes. Part 2. Syntheses of Intermediate Biphenyls and Quaterphenyls

A general procedure for synthesis of 4",6'-dialkoxy-2',2"-diamino-m-quaterphenyls has been established.Copper(I) t-butoxide is used to prepare 2,6-dinitrophenyls from 1,3-dinitrobenzene and aryl iodides.One of the nitro-groups is then exchanged for a methoxy-group by sodium methoxide in hexamethylohosphoramide; the resulting 2-methoxy-6-nitrobiphenyls are then iodinated in the 5-position.Ullmann coupling then gives the dinitroquaterphenyls which are reduced to the diamines.An alternative route from 2,2',4,4'-tetranitrobiphenyl was explored; arylation was easy but alkoxydenitration was indiscriminate.Some 71 new derivatives of biphenyl, terphenyl, and quterphenyl are reported.
