Palladacycles, Buchwald-Hartwig amination

A plausible mechanism for the one-pot synthesis ofcarbazoles is shown in Scheme 5. It consists of two interlinked catalytic cycles. In the first cycle a classical Buchwald-Hartwig amination reaction occurs to generate an intermediate 5 which then enters the second cycle by oxidative addition to Pd(0). The resulting Pd(II) complex then undergoes intramolecular C-H activation to give a six-membered palladacycle which subsequently yields the carbazole by reductive elimination. [Pg.241]
