Cyclic Amines Similar to cycloketones [reaction (6.43)], the first step in the fragmentation of ionized cyclic amines is a-cleavage of the C—C bond next to the C—N bond to produce a distonic ion [20]. Subsequent fragmentation proceeds via the loss of an alkene molecule or via an H-transfer followed by the loss of an alkyl radical. A typical example of the latter fragmentation is the loss of an ethyl radical from the cyclopentylamine radical cation. Ionized cyclic amines also exhibit an abundant (M - 1) ion from loss of the a-H (see Figure 6.8). As exemplified for piperidine, cyclic amines also participate in these generic fragmentation reactions of heterocyclic compounds [reaction (6.42)]. 

This book provides a detailed, up to date account of the reactions of chlorosulfonic acid with aliphatic, aromatic and heterocyclic compounds reactions with elements and inorganic compounds are also discussed, along with the use of the reagent as a powerful acid catalyst and a halc eiution and dehydrating agent. Finally, the commercial uses and manufacture of chlorosulfonic acid are reviewed.
