Literature References
Can be used as a carbocation scavenger in the acid-promoted deblocking of peptides, e.g., t-butyl cations in the cleavage of N-Boc groups with TFA: Coll. Czech. Chem. Commun., 55, 1792 (1990). Similarly, has been used as an additive in the cleavage of O-benzyl and N-Cbz (Z) groups: Chem. Pharm. Bull., 35, 3438 (1987). See also Appendix 6.
Applications
Pentamethylbenzene is used to prepare a mixture of nitropentamethylbenzene and 2,3,4,5-tetramethylbenzyl nitrate1. It was also used to prepare propene.
