| Abstract
| - Mechanistic investigations and protocols for the synthesisof 2-nitrobiphenyls and 2,2‘-dinitrobiphenyls are disclosed.It is revealed that obstacles appear during the transmetalation step when the phenylboronic acid is substituted witha nitro group in the 2-position, whereas when substitutedin the 3- or 4-positions, the reaction follows similar patternsas found in the electrophilic substitution of nitrobenzenes,an observation that may be attributed to the elimination stepof the catalytic cycle.
