Two of these functional groups are substituted onto a molecule of naphthalene to create a proton sponge. They’re not epoxides, but reaction of this functional group with mCPBA gives syn alkenes due to the cyclic 5-membered transition state in the Cope elimination. Reaction of this functional group with benzenesulfonyl chloride followed by acidification in the Hinsberg test allows distinction of the degree of substitution. Primary examples of this functional group are formed from alkyl halides in the Gabriel synthesis. Carbonyls can be converted into this functional group in one-pot reductive reactions. For 10 points, name this functional group consisting of a nitrogen atom single bonded to at least one carbon atom. ■END■
