Literature References

Use of p-toluenesulfonamide as a derivative of ammonia activated to alkylation by alkyl halides is exemplified by the synthesis of N-tosyl-2,3-dihydroisoindole from o-xylylene dibromide: Org. Synth. Coll., 5, 1064 (1973). Similarly, has been used as the precursor of nitrogen-containing crown ethers; see, e.g.: J. Org. Chem., 53, 5292 (1988). Precursor of N-tosyl imines, which are useful intermediates in synthesis: Synlett, 2097 (2003).
