Fig. l.-Structural formula of fluorene. the nitrogen atom and largely on the basis of this fact it has been suggested5 that the migration of the most electronegative group attached to the carbon atom would in general be favored. The rearrangement of intermediates formed from tertiary methyl nitrogen derivatives, where two of the groups attached to the tertiary carbon atom are linked together, as for example in a 9-substituted 9-fluorylchloroamine (11), has ...
