1,1-Dimorpholinoethene and 1,1-dipiperidinoethene condense with such compounds as malonitrile, ethyl cyanoacetate, cyanoacetamide, and diethyl malonate to give the corresponding β,β-disubstituted enamine, a molecule of morpholine or piperidine being eliminated in the process.Similar reactions with acetylacetone and ethyl acetoacetate proceed with loss of the acetyl group to give the β-enamine. 1,1-Dipiperidinoethene and nitromethane give the β-nitroenamine.Secondary process of either hydrolysis or further Michael addition and elimination are noted in condensations of 1,1-dimorpholinoethene or 1,1-dipiperidinoethene with cyanoacetamide under more basic conditions. 1,1-Dipiperidinoethene is arylated at the 2-position by 2,4-dinitrochlorobenzene.

Some amides of acetoacetic acid were synthesized by reacting secondary amines with acetoacetic ester at 150 deg C.It was shown via PMR and mass spectrometry that the amount of the enol form is higher in the amides than in acetoacetic ester.
