HCID 14003990, compound → N-Methylcarbazole

Participants

Reaction Steps

Perhydro-N-methylcarbazole is catalytically dehydrogenated over a supported Pd or Pt catalyst to provide H2 and N-methylcarbazole (FIG. 6). Sequentially, the N-methyl group is oxidized with air using a copper halide catalyst to yield the N-formyl compound Ill. Because of the very high heat of this oxidative transformation, only an approximately 20% conversion of (II) to (III) should be necessary to provide for the heat of dehydrogenation.
