A solvent-free method for the addition of amines to dialkylacetylendicarboxylates or alkylpropiolates using a planetary ball mill was developed. Conversion of educts was quantitative within five minutes without use of any catalyst or base. Beside the E-/Z-isomers, no side products were formed. addition - amines - alkynes - enamines - green chemistry
