methyleneamino
Methyleneamino refers to a chemical substituent or functional group that consists of a methylene unit linked to an amino nitrogen, giving the fragment -CH2–NH–. In this arrangement the methylene carbon is connected to the main carbon framework, while the nitrogen bears at least one hydrogen or another substituent. The group is commonly encountered as a linking unit in secondary amines, where the nitrogen carries one hydrogen and one carbon substituent.
Nomenclature and context: The methyleneamino fragment is often described simply as a methylene bridge to an
Preparation and occurrence: A typical route to methyleneamino-containing compounds is reductive amination, where aldehydes or ketones
Reactivity and properties: As a secondary amine motif, the methyleneamino group participates in standard amine chemistry,
