Abstract In this article, a study on reactions of tertiary allylic amines and dichlorocarbenes had been described. Tertiary allylic amines could result from an interesting de-N-allylation/formylation reaction under the treatment of dichlorocarbenes. Notably, amines containing steric substituents or electron-deficient aromatic substituents on the nitrogen will go through cyclopropanations of the carbon–carbon
A cationic (CAAC)gold(I) complex promotes the addition of all types of nontertiary amines to a variety of allenes, affording allylic amines in good to excellent yields; the amino fragment always adds to the less substituted terminus of the CCC skeleton.
