Its use in organic syntheses stems from the fact that it can react with an aldol or ketone to form a carbon-carbon bond in the Henry reaction as well as act as a Michael donor in 1,4-Michael additions.
In the polymerization of polyetherimides, this compound is surprisingly readily displaced by bisphenolate ion. One of the few organic compounds to contain this functional group is chloroamphenicol, in which it is found as an aryl substituent. Its use in organic syntheses stems from the fact that it can react with an aldol or ketone to form a carbon-carbon bond in the Henry reaction as well as act as a Michael donor in 1,4-Michael additions. As a substituent on benzene rings, it acts a strong deactivating group and as a director of meta substitution. This functional group can be reduced to a primary amine via catalytic hydrogenation. For 10 points, identify this functional group that consists of a nitrogen bound to two oxygen.
