Protecting Groups

Protecting an amine as a carbamate therefore enables other functional groups to undergo selective reactions with electrophiles whereby the carbamate (protected amino group) is left intact However two additional synthetic steps are needed to achieve this protection: the step to form the protected intermediate and a deprotection once the additional selective synthetic steps have

SPECTRA DATABASES

If you use a spectrum from one of these databases to compare with your experimental spectrum do not choose one that was determined in the gas phase (unless your spectrum was also determined in the gas phase) NIST WebBook: National Institute of Standards and Technology This site contains IR (gas phase mostly) Mass Spectra and a few UV-visible spectra
